during the time he spent abroad. disturbing developments tonight, as the people of manchester tried to come to terms with terror. guest: -- reporter: a city in morning as residents pay their respects to the dead. >> i think it's the defiance of manchester, the life very much goes on. we never forget, but it's one of those things where the city doesn't stop. >> it's the same with berlin, the same as paris, the same as nice. it's all over the world how do you defeat these people? you can't. all you can do is be vigilant and carry on as normal and don't let them win. reporter: police identify the suspected bomber as 22-year-old salman abedi. he was bormanchester by libyan . investigators are now hunting for accomplices who may have helped him build a suicide bomb.

>> i think it's very clear that this is a network that we are investigating. extensive investigations go on, and activity taking place across greater manchester as we speak. reporter: this is where abedi lived. heavily armed police raided his properties in the neighborhood. they have made a number of arrests. the city's muslims have condemned the attack. but the community remains on the edge, amid reports of hate crime's. -- crimes. >> we are concerned about reports we are receiving, reports we are receiving about anti-muslim acts. these are terrible anti-muslim acts, ranging from verbal abuse

to acts of criminal damage, to mosques in the area, and outside the area. reporter: in london, soldiers have been stationed at key locations. britain has raised its terror threat level to critical, meaning another tack could be imminent. -- attack could be imminent. brent: we are joined now via skype by terrorism and security analyst david and liverpool. -- in liverpool great "the new york times" posted pictures on its website that it says shows remains of the backpack bomb was in. what more can you tell us about that? reporter: i've had a look at it. quite a sophisticated advice, when you do need expert knowledge. i am no technical expert.

this isn't my area of true expertise, but you look at that and you put it with all the other information, you can see abedi was not acting alone, has been working with other people, and this is why the u.k. is a critical because there's a fear that the individual who may have put this device together is still at large, could put a similar device together, and could get someone else to use it. we can see the devastating effects of it on monday evening. quite surprised this is being released. i'm sure there will be a nation of how "the new york times" got a hold of it. brent: we've had a lot of developments in this story. the main suspect's brother and father, they've been detained. is that unusual that we are looking at possibly an entire family they could be behind the

terrorist attack? reporter: i suppose if you look at other terrorist conflicts and other areas, it isn't unusual. i think where we got used to in europe, certainly over the last few years with groups like islamic state, we see individuals from family going to a region. you look at what's happening. it is unusual, and obviously there has been support from authorities in libya. don't forget libya has its own political problems, it's been having a civil war since the fall of gaddafi. and it shows you that this is an international threat. it is of an international nature. brent: we are also hearing reports that possibly so-called islamic state could be behind us -- this. there are reports the suicide bomber had just returned from libya, he had also been to syria.

is this tgedy from monday night, is it part of the nexus we are seeing of global terror from syria, libya, and then making its mark in britain? >reporter: well, there's a numbr of strands there. it does show that relationship of the international terror. you look at islamic state, it's been losing territory. those foreign fighters, those who came from european states, they are looking to return home. not all those returning home want to carry out a terrorist attack, but here's the fear. those that are well-trained could pose a great threat. obviously you are traveling to libya and syria, it has to be questioned. this is no doubt why people get on information systems, intelligence systems.

why you go to these regions when the conflict is so high in these particular countries. normally we've seen attacks by lone actors and groups like islamic state will claim respsibility. it may be a little bit not so much direct order or direct control, but you can clearly see there's some people really and vetted within the narrative, this extreme islamist narrative. brent: david in liverpool, thank you very much. we appreciate your insights tonight. reporter: you're welcome. brent: u.s. president donald trump has met with pope francis in rome as part of his nine-day tour. the two had clashed publicly on issues in the past ranging from climate change to migration, but they seem to have put their differences aside at a successful meeting in rome. trump later arrived in brussels, where he will meet with leaders of other nato member countries

for a summit of the military alliance. good evening to you, baron. a high-level nato summit kicks off tomorrow. president trump has been very vocal about nato burden sharing, repeatedly bringing up the issues of members not paying their fair share to nato. what is the meeting going to be like considering all of that? reporter: for the public, this is a short summit, only three hours. it is designed to be a display of harmony and unity across the atlantic, but behind closed doors, donald trump, the new president might ask for more money as he always does when he meets allies, and the allies will patiently explain again and again that they are already on track to meet the spending goals nato set for its members.

there are no dues or debt to be repaid because nato does not work in that way. nato has no common budget, there are no fees you have to pay. nato will hope that donald trump might understand this. brent: reports emerging today that nato will join, will formally join the anti-isis coalition. what are the tasks for nato within that coalition, do we know? reporter: the tasks for nato would actually not change. nothing would change on the ground, because you have to recall this anti--isis coalition has 60+ members. the european union is a member parted -- member. on the estates are members in this coalition and doing what they can do up sharing fighter jets and boats and also boots on the ground to educate people in iraq and other places.

so nato would only coordinate its more or less symbolic gesture to give trump something he can gain and obtain something he would process. it is a little present for donald trump, but not a big deal for nato. brent: baron, thank you very much. 100 days ago, german turkish reporter was arrested and detained in turkey and he's been behind bars ever since. he is one of more than 150 journalists jailed since last july's failed coup. turkey now detains 1/3 of imprisoned journalists worldwide. the 43-year-old's wife published a letter talking and sharing her distress. she writes, i've been without him for 100 days. the biggest similarity between being inside and being outside

is that you count the days. every monday as i make my way, step-by-step, through the prison to dennis' cell, each metal bar ipass punches a hole in my heart . and when visiting time is over and we waved goodbye and i turned to go, that false smile i was wearing suddenly disappears. calls for dennis' release have been growing, but there is no sign that he will be released anytime soon. here's more on the case that has sparked international outrage. >> 100 days behind bars. the #free dennis emblazoned's the roof of his newspaper's building. because he's been silenced. turkey says he's being held on suspicion of producing terrorist propaganda and incitement to

hatred. his friends and family immediately began publicizing his case. without having been officially charged and without any court proceeding so far, he's in solitary confinement in istanbul. >> as family members, we want to show solidarity today in his hometown. and of course we hope the pressure rises so that deniz is released as soon as possible. reporter: but how much pressure can they exert? the relationship between berlin and ankara has been testing for quite a while. but yucel may become a test case. >> angela merkel once as to free a terrorist agent -- wants us to free a terrorist agent.

i told her we have a justice system. he will be put on trial and once the release for his trial -- won't be released before his trial. reporter: besides yucle, more than 150 journalists are being held in turkish prisons. germany has been pushing for yucel's release. it at least managed to gain consular access to him in prison. but it says being held for months without being charged as a human rights violation. >> let us make no mistake, it is not in accordance with rule of law if an executive, in this case turkey's executive, free judges and individual as it is publicly done to deniz yucel. and the pressure on the german government isn't letting up either. at a public reading of yucel's

books on sunday, peace prize winner -- a peace prize winner added voices to the chorus demanding yucel's release. brent: he will take a short break. -- we will take a short break. when we come back, more headlines. stay with us.

brent: welcome back with "dw news" life from berlin. it's being reported that two brothers and the father of the suspected manchester suicide bomber had been arrested. when brother was allegedly planning a terrorist attack in the limiting -- libyan capital tripoli. authorities also confirmed they are investigating a network that supported the manchester attack. u.k. has raised its terror threat level to critical. u.s. president donald trump and the first lady have landed in brussels after meeting with pope francis at the vatican.

the two men had traded birds during trump's show campaign last year but at this meeting they exchanged gifts. the president is on the nine-day overseas trip. javier is here now with the business news. reporter: it's a story that is just starting to develop. we have to keep in eye on that. despite efforts by the white house, voices saying donald trump is hiding something regarding his ties to russia are still very loud. house democrats are now asking germany's deutsche bank to provide information on credits given to donald trump. deutsche lent millions to trump, even in difficult times. but who guaranteed them? could it be russia? that's when u.s. democrats want to find out. reporter: if you want to know who really owns buildings like this, it pays to look at the small print. a string of trump resorts and hotels were financed with loans

from deutsche bank. u.s. politicians say trump still owes the bank $340 million. what bothers them is that deutsche was still being generous to the then presidential candidate while other banks were turning their noses up at him because of his numerous bankruptcy filings. one of the loans came to $170 million to redevelop washington's old post office. so who was giving deutsche securities for these hundreds of millions? house democrats suspect russia and one clarification. congress remains in the dark on whether loan storage bank made to president trump were guaranteed by the russian government, or were in any way connected to russia. that's the pivotal sentence in a letter to deutsche from members of the house financial services committee. the suspicion is that russia may have helped to curry favor with a potential trump administration, a stunning

thought. for its part, deutsche still holding internal reviews of the trump loans under lock and key and isn't obliged to publish them, either. brent: let's bring in our financial correspondent on wall street. this is a situation that is just starting to develop. what does it mean if russia backed loans to trump, would that be illegal in the first place? reporter: you are right, there are still so many loose ends. i did talk to a lawyer earlier and she does not believe it is necessarily illegal, and if the russian guarantees for some of the loans, those guarantees would not have come from the government, from the russian government, from the russian treasury, the more likely from some oligarchs and shell companies. the whole thing might have been unethical because also the question is if donald trump should have put those conflicts of interest in the documents

when it comes to a president. at this point it looks more likely that it might have been unethical but not necessarily illegal. brent: the democrats definitely want to know what happened, but deutsche bank is not forced to reveal any information about these loans. how big a story do you think this can become? reporter: it really still depends on what we will learn in the future. a lot depends on the republican majority-run house of representatives, if they might force deutsche bank to come out with more information. well, for sure the big question these days is always might there be an impeachment of the u.s. president, and i would say that still is rather unlikely. if you look at the history of the united states, we've only seen impeachment twice. that was advertised in and i believe it was 1868 and then bill clinton in 1998. both times, at the end, both

presidents stayed in power. it is still far too early to tell how big this whole thing is, but i would say at this point it will not lead to an impeachment of the current president of the united states. brent: thank you very much. china has been downgraded for the first time since 1989. one of the big three credit rating agencies, moody's, lowered china's long-term ratings, saying the country will have difficulties getting rising debt under control. despite china's heavy influence in the asian economies, not all asian markets were concerned. >> chinese stocks initially fell on the news that moody's was downgrading the country has credit rating a notch with the shanghai composite first dropping around a point before stabilizing and making up the lost ground. the hang seng in hong kong also dipped into negative territory. but other markets in the region

initially appeared to shrug off the news. in tokyo, the nikkei was up .5% by the break, and benchmarks also gained in seoul, taiwan, sydney, and singapore. by dropping the rating, moody's show that even though growth remains around 6% in china, it doesn't think the country's government will manage to rein in its debt burden. the chinese finance ministry is unhappy about the downgrade or responded to the move by saying that modi's was exaggerating difficulties facing china's economy and underestimating efforts to reform. brent: terrorist attacks and political turmoil have severely damaged turkey's tourism sector. so, it's getting new attractions. how about a beautiful coral reef? governor of the providence of antalya just sunk a military tank for corals to grow on. that is supposed to attract fish and in turn, tourists are the tank now sits on the ocean floor, 14 meters below the

surface of the village. that's all for the business news. how is that for a dive? >> difficult taking a tank. -- tanking a tank. almost 100,000 christians have flocked to berlin for a celebration of the protestant faith. the event that happens every two years is also marking the 500th anniversary of the protestant reformation and the memory of martin luther, the man who started it all. former u.s. president barack obama is said to join the commemorations on thursday. it will take part in a public discussion with german chancellor angela merkel. reporter: increased security at the entrance to the opening service. it's a first time a church convention in germany that bags are being checked. traffic is being diverted away from the event's location to prevent possible attacks by vehicles.

nonetheless, the mood is good. >> i'm not scared. my life is in god's hands. we have to stand up and say we are for peace. we can and we want to live together peacefully. i'm not feeling too scared and by attending the church convention, i'm proving i have no fear. reporter: the church convention is a massive event, up to 140,000 people will attend countless events in the coming days. at the opening service, the priest calls for serenity and an open society. >> this church convention opens and broadens our minds for the time we live and the people we live with, for a fairer world. we want to start the celebrations briefly and trustingly, with open minds and open hearts. reporter: the president of the

german parliament picked up the church convention's motto "you see me" to make a passionate appeal. >> open your eyes, don't look away. don't walk away. don't walk away from the christian community, don't walk away from the european community, don't walk away from the democratic community. reporter: thursday march the first highlight of the convention, german chancellor angela merkel will discuss democracy with former u.s. president barack obama. for this event, security will be wrapped up even further. -- ramped up even further. brent: i talked to our religious correspondent earlier and asked him house significant martin luther's influence is today. reporter: i think the influence is really still quite big. the religious participation in northern europe has twiddled

over the last couple of decades, mainly because there's been a strong wave of secularization. at the same time, the political and cultural force of lutheranism remains very much alive, and this indeed one of the missions of the days of the church, which are celebrating now i'm a which is bringing the discussion of the social incidents and political importance of religious participation and to be open and bringing people from around germany to meet and have that conversation. brent: that was martin garrick there in front of the parliament building in berlin. the footballer you lost an appeal over a tax fraud conviction. the court confirmed the 21 month sentence which he received last year. the barcelona superstar is unlikely to go to prison. however, because sentences over two years are usually suspended in spain, he was convicted of avoiding tax and given a 2

million euro fine. here is a reminder of the top stories we are following for you, it's being reported that two brothers and the father of the suspected manchester bomber have been arrested. one brother was allegedly planning a terrorist attack in the libyan capital, tripoli. authorities have confirmed they are investigating a network that supported the manchester attack. the u.k. raised its terror threat level to critical. after a short break, i will be back to take you through the day. stick around.
