been pushing forward, in a major offensive to try and take full control of the second—largest city, mosul. the city was seized more than two years ago by the so—called islamic state. the offensive to remove them began last october, with iraqi troops securing the eastern part of the city last month. but the western half of the city is home to around 750,000 civilians, and stiff resistance from is fighters is expected. 0ur middle east correspondent quentin sommerville and cameraman nik millard are the only television journalists on the frontline with iraqi forces. they sent this report on the first day of the offensive. just after sunrise, iraq began what it hopes is its last major battle against the so—called islamic state. thousands of men, and hundreds of armoured vehicles, in a line of attack that spread for miles. the iraqi army are starting their assault on western mosul. they've breached their own defences. armoured vehicles are lining up, getting ready for the islamic state. they're only a couple of kilometres over that way, and they know that these men are coming. they're dug in, and the assault on western mosul has started. leading the attack, iraq's emergency response division, police special forces. some of these men were surrounded by is two years ago. theyjust escaped with their lives. today, they threw everything they had at is. they're now above the village, which is their main target. they're laying down fire, and they're about to call in some artillery strikes. but first came the mortars. the captain tells me there are three is fighters in a yellow building down there, and car bombs — "we're targeting them now." car bomb explosion just gone off. the men were trying to take it out, it seems like they managed to hit it. they'd set up a whole bunch of... we'll call these rifles, but as you can see here, they're getting ready with another rpg just in case. but it seems like they got it. there were four car bombs in total, but soon government forces were inside. they killed 13 is fighters, and sustained only one casualty. translation: we are very glad to have liberated this area. we have killed lots of is, and we will soon get civilians back to their homes. we will continue to push forward, and will follow is to the border. here, there were no white flags, nor is black flags. for the first time in years, iraq's flag flew above the village. the village is small, but important. it is the gateway to mosul proper, and the city's airport. and, as we discovered, homes had become fortresses. here, is weapons. and hidden inside a house, away from surveillance aircraft, another car bomb, disguised as an ambulance. the bomb inside was still live. in these streets, though, a critical advantage. there were no civilians. in west mosul, there are 750,000 people, and thousands of is fighters. it took these men just six hours to take this village, their target. they made good progress, but with overwhelming force. beyond here is another town and another village. that town overlooks mosul airport and the city itself. from here on in, though, the going won't be nearly so fast. this was a victory two years in the making. but it is more than that. these troops, once humiliated by is, today celebrated a moment of redemption, for them and for iraq. quentin somerville, bbc news, on mosul‘s southern front. well, the wider fight against so—called islamic state and the security of the region has been talked about at a major security conference in munich, and our chief international correspondent lyse doucet is there. well, iraq's prime minister was here a minute before he rushed back to baghdad to launch the start of the mosul offensive, and everyone who saw here, including british vessels, warn him that the fight is notjust military. who is going to run mosul after is is defeated there? on the ground you have iraq backed militias, us backed iraqi army, kurdish fighters. without a power—sharing agreement now, mosul will be plunged into another wave of violence and extremism. there are questions as well over what happens over the border in syria, where is is in control of rack. we heard calls in munich for american special forces to go in and be on the ground, others saying that willjust inflame tensions but one us official told me that if president trump has an america first policy, it has to be raqqa first. there are said to be is gunman, hold up in front of their computers, plotting 9/11 style attacks so here in munich a lot of talk about accelerating the fight against is, but a lot of worry that the right strategies are not in place. the white house has been trying to clarify remarks by president trump in which he appeared to suggest sweden had suffered a recent security incident. none had actually taken place. mr trump himself has tweeted that he based his comments on a fox news report about rising crime and immigration. the confusion came from a rally he held in florida, where he spoke about security issues and terror attacks in germany and france. 0ur correspondent laura bicker reports. this is a us holiday weekend to celebrate past presidents. but, in new york and elsewhere, some decided to hold protests about the new one. it has been a difficult first month for donald trump. he took time out to step into the sunshine state and hold a rally with his supporters. this is firmer ground and more familiar. the president of the united states! he promised a new immigration order later this week to replace his controversial travel ban. but some of his reasoning caused more controversy. you look at what's happening last night in sweden. sweden. who would believe this? sweden! they took in large numbers. they're having problems like they never thought possible. the swedish embassy in the us asked for a explanation. the white house says he was referring to reports of rising crime, which he may have seen on fox news. it is the kind of distraction from his message that mr trump blames on the media. i also want to speak to you without the filter of the fake news. they have become a big part of the problem. they are part of the corrupt system. president trump accused major us networks of being an enemy of the people. 0ne senior republican says lessons need to be learned from history. if you want to preserve democracy as we know it, you have to have a free, and many times adversarial, press. and, without it, i'm afraid that we would lose so much of our individual liberties over time. that's how dictators get started. but the president's chief of staff says the media is constantly making up news. they're talking about russian spies, talking about the intelligence community, talking about how me and steve bannon don't like each other, and what's kellyanne doing? this is just total garbage, unsourced stuff. donald trump held this rally to revive his message. but it is also a reminder there is work to do. president trump seems far more comfortable at the campaign podium than he does in the oval office right now. he seems to feed off the energy of the crowd. but he doesn't need to win friends here in florida. he needs them on capitol hill, if he is to get his agenda through congress. he also needs to find a new national security adviser, after his first pick resigned and his second turned down thejob. he is holding interviews today. the rally will help donald trump reconnect with his voting base, but now it is time get on with governing. martin gelin is the us correspondent for dagens nyheter, a national swedish newspaper, and hejoins me now via skype. there has been a lot ofjoking about this on twitter, but also some annoyance, hasn't there? definitely. imean, i annoyance, hasn't there? definitely. i mean, i think we started out laughing at this election, but there has also been some real concern. about freedom. we are having a little bit of trouble hearing you. i am just going to ask about the reaction by donald trump. i mean, he himself tweeted, trying to clear it up. he did seem quite irritated at how people had responded. why does he seem so sort of thin—skinned about it? i mean, i think he seem so sort of thin—skinned about it? i mean, ithink he is always... has this very antagonistic relationship with the media, and his... whenever someone criticises him, he doubles down on, you know, the thing that they accuse him of. so i'm not surprised that he is very aggressive in this. that is how he handles most, most of these situations. he does seem particularly upset. his defence secretary also saying that people are giving him a hard time for nothing. well, i mean, he has lied more than any president in american history. and, you know, we have already seen sean spicer and kellyanne conway in administration talk about non—existent terrorist attacks in america, another president himself is... we are going to have to leave it there, we have had some difficulty hearing you. we really do apologise for the technical difficulties they are. in other news: police and protestors have clashed in the ukrainian capital, kiev, ahead of a ceasefire between russian—backed rebels and government

news. this is bbc news. i'm lebo diseko. the latest headline: iraqi government forces have recaptured a number of villages at the start of an offensive to retake the western part of the city of mosul from the islamic state group. malaysian police are trying to piece together exactly what happened in the death of kimjong—nam, the half brother of north korea's leader. he died on monday after apparently being poisoned at kuala lumpur airport. celia hatton reports. the assassination of this man appears to have involved a widening cast of characters. four have already been detained in the poisoning of kimjong—nam, including a woman holding a vietnamese passport, who could be this person from the crime scene, and this indonesian woman, who said she was tricked into participating. she said she thought she was on a television prank show. one north korean citizen is also in custody, thought to be the man escorted here by malaysian police. and now the authorities have asked for interpol‘s help to find at least four more north koreans, who all entered and exited malaysia using regular passports. and i can confirm today that they have left our country, the very same day the incident happened. and more suspects are also wanted, people of interest who might know how kim jong—nam's killing was carried out. four suspects have been identified, which could assist us very much in the investigation. but still the question of what will be done with kim jong—nam's body. malaysian law requires his family to come in person to claim his corpse. the next of kin has to come forward. i have given a timeframe. and, if still they don't come forward, then we have to look for the next option. i don't discuss at the moment. we wait and see. it is unclear whether mr kim's children can travel to the morgue where the autopsy was conducted. or perhaps the law requires the presence of this man, the victim's half—sibling, north korean leader kimjong—un. south korea's unification ministry confirmed they believe pyongyang orchestrated the poisoning of kimjong—nam, the man once poised to rule north korea, before falling out of favour with his dictator father. while kim jong—nam was alive, the thinking goes, he remained a threat to his half—brother, and to kimjong—un's fragile grip on power inside north korea. celia hatton, bbc news. we heard in celia report that one of the people arrested is indonesian woman who claims she was carrying out a prank for a tv show. the 25—year—old's parents insist she is innocent and is being set up. our correspondent, rebecca henshke has been to been herfamily. siti aishah's mother, benah, says her daughter told her she had been offered work in malaysia as a model. siti, who had separated from her husband, needed money to support her son, she says. translation: she said she wanted to go to malaysia for a filming on a show, to make people surprised by spraying perfume on somebody else. she was offered a job by someone to become an advertisement model for perfume, and she's an innocent girl, that did it because it was good money. benah said she was deeply shocked when she heard that her daughter had been arrested by malaysian police in relation to the murder of kim jong—nam. malaysia media reports allege siti stood in front of kim to distract him while someone else approached from behind. her family insist she was set up. translation: i'm asking and begging for help, so that my daughter is not punished, as i believe she's innocent. before siti left for malaysia, she left here before siti left for malaysia, she lived here with her ex—husband's family. in this community, she was just one of millions of indonesians who go abroad each year looking for work, and now they're struggling to understand how she has ended up involved in such a high—profile murder investigation. translation: she was a very good girl. she really looked after her in—laws. she was very aware that she came from a village, and from a poor background, and she worked hard. i'm completely in shock. itjust doesn't make sense, and it's not the aishah i know. the indonesian government said they had repeatedly requested access to siti aishah, saying they want to make sure her legal rights are being protected. but malaysian officials said, at this stage in the investigation, that is not possible. rebecca henschke, bbc news, jakarta. the hollywood actress turned director angelina jolie says she hopes her new film about cambodia under the khmer rouge will help educate the world about the brutality of the regime. she's been talking exclusively to our correspondent yalda hakim. hollywood royalty meets cambodian royalty. the backdrop, an ancient temple. it's the biggest movie premiere this country has ever seen. the director, angelina jolie, says the film speaks to this nation's people. their actors, their language, their story. this war that happened a0 years ago, and what happens to these people, was not properly understood, and notjust for the world, but for the people of the country, i felt that i wanted them to be able to reflect on it in a way that they could absorb, so it's through the eyes of a child, and it's a lot about love. the khmer rouge, a radical communist movement, vowed to take the country back to year zero. millions were forced out of the cities in an attempt to create a rural utopia. you could be killed for practising religion, showing emotions, or even wearing colour. infouryears, 2 million people died. speaking to people here, i get the sense that they don't want to remember the past, but they also can't forget it. there are 20,000 mass graves across this country, like these ones. a visual reminder of what this nation has been through. the haunting portraits of death — hundreds of images of those who were tortured at the notorious s21 prison. more than 12,000 people were killed here. in the end, only a handful survived. 86—year—old chung mai is one of them. they beat me for 12 days and 12 nights, he tells me. i was so hungry, when i would see a cockroach, lizard or mouse, i would catch it and eat it. if they caught me, they'd beat me up again. angelina jolie is keen to tell this story and focus on this country and its past. but it's been difficult to keep the spotlight off her own personal life. we know that an incident occurred which led to your separation. we also know you haven't said anything about this. would you like to say something? er... only that... i don't want to say very much about that. except to say that it was a very difficult time, and... and we are a family, and we will always be a family, and we will get through this time, and hopefully be a stronger family for it. but this moment is about cambodia and remembering the time when this ancient culture was almost wiped out. now have a look at this glacial beauty — this is the deepest and possibly one of the oldest freshwater lakes in the world. lake baikal in southern siberia was host to the annual baikal ice marathon on sunday. more than forty russians and thirty dutch nationals took part in one of the hardest events of its type in the world. thank you for
