We begin in thailand where a nationwide manhunt is under way for a man believed to be behind mondays bombing at a shrine in bangkok.

Bangkok was rattled by another bombing on tuesday, on a pier used by tourists. There were no injuries. Thai police are looking at groups that oppose the military government, including muslim rebels in the south. Officials say the attack did not mask tactics. Scores of mourners left floral tributes and lit candles at the scene of the bombing. 20 were killed in that blast. Veronica pedrosa is in bangkok and reports from there. Reporter picking up the pieces. This is a shopping district in bangkok that has seen dramatic political conflict several times before, but nothing like this. Dozens killed on monday, among them victims from malaysia, china, hong kong and singapore. Many more injured. It was an attack designed to kill as many people as possible at a high profile target. The erawan shrine. The government is acting to restore a sense of security for the public and millions of tourists. Translation in our country theres individuals or groups of individuals seeking to destroy the country. The ongoing attempts may be politically motivated, targetting the economy, tourism, whatever reason. The government will work to find the perpetrators, bringing justice upon any networks involved as soon as possible. Reporter thai authorities released pictures of the man they believe to be the main suspect behind bombing. Wearing a yellow tshirt hes shown in the images carrying a backpack to the erawan shrine. Later hes seen leaving without the backpack. A man hunt is under way. This dash cam footage shows the moment the bomb went off. 5 kilograms of military grade explosives that sources told al jazeera was deliberately detonated. Within hours of the blast the militaryrun government was blaming the political enemies. Now its asking the country to unite and stay calm. We would like to once again assure the public, look at what happened after this. What happened. But after this the Thai Government will do our best to make sure everyone is well looked after. Reporter but within an hour of that speech this happened at the main pier for river transport another highprofile tourist target. The grenade landed in the water, and no one was injured. Back at the erawan shrine, things are getting back to normal. The roads have been reopened. This is as close as we can get from the shrine. Security has been tightened. We have seen forensic teams arrive as they try to get to the bottom of how and why this brutest attack happened. Thai authorities will not say how soon theyll be able to announce the results of their investigation. Joinings us from washington, retired Army Lieutenant michael walsh. Good to have you with us. Thai authorities moved quickly. That footage of the bomber, it seems that they are sure that its their guy. The video is not terribly clear. Is it enough for them to find him by publicizing it widely. Well, a few things are going on right now, and the thai services, Law Enforcement and intelligent sources, as your piece mentioned, not only experienced a deal, but are fairly capable. What you are what you should see now is, one, the Government Service publicizing any information that it has, trying to get it out there as quickly as possible so that anyone that recognised some key features, the yellow tshirt, the young man that walked through, could immediately notify police. At the same time authorities should be cordoning off the area, and theres a lot you can tell from the type of explosives, and the type of bomb. Everything from fragments from where the materials could have come from, to the explosives themselves, to the type of detonators, how it was detonated, that could not only leave different types of indicators, and kind of make the trail get a little hotter, but certain groups are known for certain types of attacks. Certain types of bombs, and certain levels of sophistication that they could make. We have seen that the authorities kept out the muslim rebels down in the south. Talking about those groups, as far as we know no one claimed possibility. So what do you think who are the most likely suspects . Well, you know, look, i think everything should be on the table at this point. When what you do in these types of situation is begin to narrow the scope. You know, there was mention of thailands immense political instability in various groups there. This is a bit unusual. Typically the attacks from those domestic, political and paramilitary groups targeted things like empty police buildings, or areas that no one was, you know, actually in, certainly not as populated an area as that shrine. This is the first time we have seen an attack target large numbers of civilians in a long time in thailand. Right. It could be an International Group as well. There is some speculation that the thais recently sent away a number of uyghurs, the chinese muslims, and, you know, it could be some type of retaliation for that. This was eerily similar in the boston bombing and the back pack used there. Could it be a lone wolf . Certainly it could be. It could be something that we see similar to the United States, and terms of lone wolf inspired online by i. S. I. S. And other groups and a political group. And with a proliferation of the internet and a targetting of certain demographics by the group. I wouldnt put it out of the realm of possibility at all. The state department and Intelligence Services and Law Enforcement likely are looking into this china is investigating the head of its Workplace Safety agency following last weeks explosions killing 114. Officials said the owner of the warehouse that blewup did not have a licence for chemicals.

Thousands of migrants straight to get to england will gather there. Meanwhile, the European Union is promising to get greece more money to deal with a large number of migrants. Many are showing up near turkey. Jonah hull is there with more on the growing tensions with the migrants. Reporter if this is a promised land, for many its proving false. Every day they come, sometimes in their hundreds. Refugees and those seeking Work Crossing the placid waters from turkey, from a turkey tonne. And every day they wait for paperwork that allows them to stay or move on to other parts of europe. Iraqis assist here, african is here, but there is little procedure. Reporter others have been waiting longer. Much longer. Reporter how much. 23 days. Reporter 23 days, and no one has helped you in that time. I want to go in germany.

You, yourself, should know that we are africans. Reporter on the greek shore they may be safe from the hardships they fled. But here, floating on a holiday lie low, they are far from secure russias president Vladimir Putin blames the ukranian government for increased fighting in level held areas. Vladimir putin is on a 3day tur to promote tourism. Firstly diving in a mini submarine for a close up view. Then he surfaced saying kiev was behind skirmishes in the east. He said the minsk Peace Agreement will bring peace in the east another democratic senator is breaking ranks with president obama. Senator bob menendez will oppose the agreement. As Mike Viqueira reports from washington. It may not be enough to sink the deal. Thank you. Reporter its another blow from another senate democrat. New jerseys bob menendez says he will vote against president obama on the iran deal. At the end of the day we appear to have a rollback of sanctions and iran limiting its capability, but not dismantling or rolling it back the menendez announcement was not completely unexpected, but provides a window, creating a campaign to win support for the deal. Joining menendez Tennessee Republican bob corker, chairman of the Foreign Relations committee, writing in an op ed with a vote rejecting the deal, both are busy counting congressional votes, an inexact science. This much is clear, a majority of the house or senate will vote to reject the deal, bringing a certain veto. The big question, can opponents muster twothirds in both houses to override the veto . It will be close. President obama has kept up the pressure, seeking support from lawmakers by phone, dispatching touch officials and taking his case to social media. Opponents are spending millions in a multipronged attack to kill the deal. The president has only 12 democrats to spare. Thus far he has lost two. Really schumer and now menendez. Its a similar story in the house of representatives, one republican thinks the president will win. Senator Majority Leader Mitch Mcconnell said on monday that president obama has a likelihood of success in the upcoming vote. The other side has its politics. Irans parliament holds its own vote. The Supreme Leader says the fate of the deal is unclear and assured iranians if approved, it would not bring undue influence. We will not allow economic penetration or political or cultural penetration or presence into the country by the United States secretary of state john kerry has been working the phones. In the face of the menendez defection, kerry once again made the case for approval. It makes america safer, not to mention israel.

Coming up a look at the lives of brave aid workers who risk it all in war zones around the globe. Later, the controversy and political fight over Julian Assange. I speak to his lawyer about the allegations against him, some of which have just expired. The United Nations is paying tribute to aid workers, those that put their lives on the line to help those in conflict zone. The aid agency tomorrow observes world humanitarian day.

In our in context segment. Jennifer glasse in kabul on some of the riskiest work they are doing. Reporter this is one of the most dangerous jobs in the world, looking for mines rockets and other unexploded devices. It calls what is below ground the hidden enemy. There are plenty of other dangers. We were working on a hillside. The taliban came from the other side, surrounded the team, captured us and said bad words. Then they cocked the weapons and threatened to kill us. That time they were released. 12 colleagues in Helmand Province were not as lucky, shot dead last september. Because of the nature of their work means they are in contested areas, these are some of the most targeted aid workers, operating in difficult places. There are thousands of fields like this all over afghanistan, yet another danger that humanitarian workers face. The main threats are abductions, robberies, intimidation, improvised expleasives and explosives and small arms fire. The head of the mine cord in my submission unit said one of the big problems is theres so many different groups fighting, its hard to know who the is best local contact. And the government is not much help. In some cases if we ask the government to support us, its counter productive. They cant provide enough security, and we are in and out with it being onesided, and thats making that is making our life more difficult monday morning, a german aid worker abducted at gunpoint. And the dangers continue here. The u. N. Says 37 acres have been killed so far this year the group aid workers security tracked a number of attacks on humanitarian workers. It found in 2013, 190 violent incidents against aid workers. 229 workers were impacted. 120 killed, 88 others injured. As i mentioned, afghanistan is behind the highest number of attacks taking place on humanitarian workers, followed by syria, south sudan, Central African republic and pakistan. The numbers from down from recordsetting highs in 2013, when 436 workers were targeted. Its believed the drop was due to a lower number of humanitarian workers sent to unstable regions. To help us put this in context, we are joined by the c. E. O. Of hunker u. S. A. Good hunger u. S. A. Good to have you with us. Your organization sends aid workers to dozens of country, numbers were better last year than 2017, the last two years is the worst ever. Is it hard to get people to go. Yes, its been the worse ever, i dont think its hard to get people to go in those areas. 90 of our staff is national staff, from the country where we work and are committed to working there. It is, indeed, difficult to make sure they are there, and they manage to work in security, thats the biggest challenge we face. Is it harder to get them to go to the most dangerous countries, especially the ones we mentioned. There are countries that aid organizations dont go to at all. It is a challenge, and theres a good publication called stay and deliver. It allows them to stay and deliver their aid. The biggest complication is to make sure that we do it in safety and assess the population in need. The workers are a vehicle to success. Does it impact you when you see attacks like the one in afghanistan in june that killed nine people. It does. What is important. Every time an intent occurs, we are able, quick to analyse what has happened, the incident report, checking security thresholds, continuously we have to do security to make sure we keep up with the changing environment. Is kidnapping one of the biggest issues, because some violent groups are turning to ransom money as a way to finance operations. It is definitely a big issue for humanitarian agencies, and a big concern, yes. How big an issue is it from a financial stand point for organisitions like yours to provide security. That is controversial, something that the organization is uncomfortable talking b theres rules prohibiting paying ransom. Aside from ransom. Its a significant part of what you have to pay for to keep your people safe. Its not a cost. Most agencies, we do not have security in terms of armed guards. But i think most of the work is to guaranteed acceptance from the population. Most of the activity invests time and energy to make sure that population understand the principle. You are there to help them. That they will help you. Exactly. And make sure the concept of newt reality, independence is clir. Are you increasing Safety Training for the people. They know how to behave. Definitely, theres a big investment on that one. Sometimes we do it internally. Sometimes we go to specialised agency.
