Led to an unprecedented rise in the murder rate. Around 2,000 people were killed in just the first two months of the crackdown. Jonathan head reports on the philippines deadly war on drugs. The war on drugs is reaching all corners of the philippines. Even here, in the jails. Many of these men are already serving long sentences for drug use. In cells, so packed with bodies, its hard to breathe. It says something about the extent of the drug problem here in the philippines that the police have had to come here and raid one of the biggest prisons around manila. There are clearly concerns about real Drug Problems here. The focus, as with so much of this campaign, are the people at the very bottom of the trade, not the people running it. At least here they can stay alive. But not here. The bodies of dealers and addicts are discovered every night in the slums of manila, killed either by the police or by shadowy hit squads. It started when this man, an outspoken Crime Fighting mayor was elected president in may. When he said he would kill drug dealers, he meant it. Thats the lives of ten criminals really matter to me . If i am the one facing the grief, would 100 lives of this idiot would mean anything to me . The president is still wildly popularfor this kind of talk. Drug addiction has blighted neighbourhoods, already burdened by poverty. But his campaign has forced roger, not his real name, into hiding. Hes been a minor drug dealer for years. Now hes on the run. Translation ive done some awful things i know. Ive wronged a lot of people because theyve become addicted to drugs because im one of the many who sells them drugs. Not everyone who uses drugs commits crimes. Me, im an addict. But i dont kill. This chilling Security Camera video shows why those targeted by the antidrug campaign have so much to fear. A motorbike slows down for a moment. The Passenger Firing at point blank range. It might easily have been maria, a young mother and a hired assassin. She says shes killed five people since the president won the election. Like roger, she says it was poverty that drove her into the job. Translation i tell my husband that we cant keep doing this forever. We have children. I would not want our children to know what we do. I do not want them to come back at us and say that they got to live because we killed for money. Nearly 700,000 terrified drug addicts have already surrendered to the Philippines Police to save their lives. They must somehow now be accommodated in these teeming, overcrowded cells. The iraqi city of mosul waited for deliverance as iraqi and Kurdish Forces battled for two months to liberate the last strong hold of so called Islamic State in the country. As the troops continued their drive towards the city, the militants fought back using suicide bombers. At the start of the siege, orla guerin and her cameraman were among the firstjournalists to get into the village on the outskirts of mosul as it was being liberated from is. A harbinger of terror. We entered hostile territory, taking the battle to is, with Kurdish Peshmerga fighters. This was their second attempt to free this village. Last week they faced heavy resistance. Along the way, tension building, as we start to come under fire and to respond. Were moving forward now very slowly and carefully. Were hearing quite a bit of outgoing fire. The troops are trying to gauge how much resistance is in these villages. This was the answer. A massive Roadside Bombjust ahead. It was one of four on our route. Then the peshmerga moved to confront a suspected suicide bomber. They have to check him for explosives with their bare hands. This time they were lucky, just a civilian. We arrive in what looks like a deserted village. Locals start to emerge, tentatively to offer thanks, but soon, this. Gunfire warning shots from weary troops. Wary. At last, freedom and relief. Theres nothing to worry about, he says. Its all over. But theres a legacy of torment. They destroyed us, says mohammed. They completely destroyed us. There was a sense of a Community Coming back to life, of old friends reuniting, freed from the tyranny of is. A moment of victory for the peshmerga. And for some here, of rebirth. I cant find words to express how happy i am, he said. It feels like i have been born again. Nearby locals attacked an is sign that had loomed over them, instructing women to cover themselves from head to toe. Amar was happy to be wearing her best and not wearing a hijab. As this woman thanks the peshmerga, is make their presence felt, not far away. Gunfire helping to secure the village, a volunteer sniperfrom scotland. Hes fought with the peshmerga since 2014 and has been part of the recent push against is or daesh. Its kind of funny because places that are weak, places theyll stand and fight. Theyre very up and down. Youre talking a lot of these people cheering now would probably daesh. Theyve just gone back into their community. So they havent gone away. Even as they celebrate, the troops know their enemy could soon re emerge. The peshmerga are moving through the village. Theyre securing the area street by street and more and more civilians are appearing. They can speak freely for the first time in over two years, but there is still some tension here. The fighters are concerned that among those coming out onto the streets there could be suicide bombers. But there were no threats concealed among the villagers. They were savouring the chance to reclaim old pleasures, banned by the jihadis. The black flag of is has been pulled down from the mosque. The peshmerga vowing never again will it be allowed to fly here. Heres a thought, imagine surgery but without knives or scalpels, just sound waves. Thats what doctors at a hospital in london have used to operate deep inside the human brain. The pioneering treatment was performed on a patient who suffered from uncontrollable trembling in his right hand. It could also be used to control the tremors caused by conditions such as parkinsons disease. Over the past something years its got worse and worse. Selwyn is a painter and decorator. Hisjob is made increasingly difficult by this, an uncontrollable tremor in his right hand. The shaking is caused by a mistiming of the electrical signals, the commands sent from the brain to the muscles in the hand. One Million People in the uk sufferfrom tremors. The last 15 years its gradually got worse to the extent i cant use it. Ive got to use my left hand. Early morning at St Marys Hospital in london. And selwyn is being prepared for deep Brain Surgery. But this razor is the only blade that will be used today. This frame will ensure his head is kept completely still during surgery. Once it is placed inside this machine, the first of its kind in the uk, which operates using sound waves. It works like this the device has more than a thousand ultrasound beams. When focussed on a single point, they generate enough heat to destroy tissue. The target is a tiny point at the base of the brain, which is causing the faulty signals, which trigger the tremors. 697 watt, 13 seconds. This is precision medicine. The team constantly monitor mri scans and gradually increase the energy of the sound beams. Selwyns wife is there to re assure him. Ive witnessed quite a lot of Brain Surgery and it is brutal and bloody, drilling through the skull and cutting through tissue. The contrast here is astonishing. There are no scalpels, its all done with sound waves and the patient is awake throughout. And the result remarkable. The tremors have gone. His right hand is steady and this is a permanent fix. Doctors believe Ultrasound Surgery could treat other conditions. It could help involuntary movements in parkinsons and help tremor in Multiple Sclerosis as well as other neurological conditions emanating from the brain. It has a big future . An enormous future. This was selwyn before treatment. And after. It avoids the risks associated with conventional Brain Surgery. And recovery is immediate. Youve got a big smile on your face. Yeah. Its nice isnt it. Brilliant to pick something up with that hand and know its not going to spill everywhere. Selwyns treatment is part of an international trial. Once thats completed next year, theres likely to be huge demand for this pioneering surgery. A really fascinating insight into the life of the penguin now. Scientists in antarctica have been working on a Ground Breaking project to capture the activity of a colony of penguins on camera. They spent much of the year watching them using remote cameras to see how theyre adapting to Climate Change and of course the threats they now face. Victoria gill was given exclusive access to their research. Her report contains flashing images. Im in antarctica following a team of scientists setting up remote cameras in Penguin Colonies here. Im tom, a scientist at oxford university. Weve probably got a0 and they are spread out the length and breadth of the peninsula. The bottom one, that takes photos all year round, every hour. The whole reason were here is to monitor penguins on a vast level. If we have a constant presence in all these colonies, we can look at how many chicks survive. Its like cctv. Seeing was going on in winter is something you would never get to see. The partnership with tourism, this access is really important, isnt it . Its vital. We would never have the access without them. Partly were doing this because theres a potential threat and we want to measure it. Where weve looked, there seems to be very little impact of tourism. We have quite a Close Partnership and they drop us off where we want to go. In return, we educate their tourists about conservation and hopefully inspire them to conserve penguins. This is the gangway. Before we go ashore, we have to wash our boots. Its a pristine place. We dont want to take anything onto the antarctic mainland which shouldnt be there. This is the zodiac, its a rubber boat. We use this to get around. Theyre fantastic boats, very fast, very stable. They bounce when you hit them up against a rock. Theyre wonderful for down here. I work as expedition leader. Its incredible to see how ubiquitously everyone is affected by antarctica. One of the things that we love about working with the production
