hopefuls who their favorite living u.s. president is. it may surprise you. welcome to our viewers in the u.s. and around the world. i'm atika shubert in london. and this is "cnn newsroom." back again in boston, where dzhokhar tsarnaev has been sentenced to death. the 21-year-old admit head was responsible for the boston marathon bombings. a federal jury convicted him on all charges just two weeks ago. on friday, he stood quietly and showed no visible reaction has the judge announced the reaction. >> reporter: today, the jury has spoken. and dzhokhar tsarnaev will pay with his life for his crimes. >> two bombs exploded near the finish line of the boston marathon on that april day, killing three people and injured

more than 240 others. now, we won't know where tsarnaev will stay while he's on death row, until the judge formally sentences him. that date has not been set. one option is the u.s. max prison. that is home to ted kaczynski and shoe bomber richard reid. >> even in the wake of horror and tragedy, we are not intimidated by acts of terror or radical ideals. on the contrary, the trial of this case has showcased an important american ideal, that even the worst of the worst deserve a fair trial and due process of law. >> the courtroom in boston was packed with people who survived the 2013 attack. 17 people lost limbs when the pressure cooker bombs exploded sending bb pellets, nails and

other shrapnel into the crowds. some spoke outside the courthouse. >> there's nothing happy about having to take somebody's life. i'm satisfied. i'm grateful that they came to that conclusion, because for me, i think it was the just conclusion. but there's nothing happy about any single bit of this situation. >> i'm sure at one time in his life he was a very lovely, caring young man. what he turned into, obviously, was -- we know what he turned into. he turned into a monster. >> there's justice now, he wanted to go to hell, and he's going to get there early. >> one thing that's still a mystery in the boston marathon bombings is whether catherine tsarnaev played any part. cnn's drew griffin reports. >> reporter: immediately after the bombings, catherine russell

slipped from public view with her small child. with her parents in rhode island. to her neighbors she was seen like a ghost. rarely seen and never heard from. >> she's trying to remain out of public view. trying to figure out who she is and trying to raise her daughter whose father was a mass murderer. and that's got to be a challenging task. >> reporter: there was also the question, too, of what she knew about her alleged husband's role in placing the bombs. bombs that were at least partially made on the kitchen table of the tiny apartment she shared with tamerlan tsarnaev. catherine russell was never

charged. former federal prosecutor says regardless of what she did or did not so, it's smart for her to remain silent. >> unless she aided or abetted, went out and purchased some item that she knew she was using to build a bomb, she's not guilty of any child. >> reporter: kathryn was seen holding what is believed to be the latest child, a niece, the daughter of her 24-year-old sister-in-law. aclean that tsarnaev recently appeared in court of unrelated charges of threatening a romantic idol with a bomb. her last known apartment was just blocks from the last listed address of alina and bella tsarnaev, sisters in law.

the tsarnaev families believe brothers tamerlan and dzhokhar were incident, set up in some type of con spiracconspiracy. but her family says she's not talking and will not talk. drew griffin, cnn, new jersey. back to the latest developments in the deadly amtrak train derailment in the u.s. city of philadelphia. an assistant said she heard brandon bostian say the train was struck by something just moments before it hit the track. another engineer reported something similar happening to his train. >> you recall that the septa engineer had reported to the train dispatcher that he had either been hit by a rock or shot at. and that the septa engineer said that he had a broken windshield and he placed his train into

emergency stop. she also believed that she heard her engineer say something about his train being struck by something. >> the fbi is now examining the train's shattered windshield for clues. federal investigators interviewed amtrak engineer brandon bostian for the first time friday, saying he was extremely cooperative, but long before his train flew off the tracks at 106 miles per hour, bostian ranted online for the industry, he slammed officials for not using a well-known system to prevent this type of tragedy. the funeral for the youngest victim navy midshipman justin zemser was held friday in new york. u.s. lawmakers have used this crash to reignite the debate over the federal

infrastructure. tom foreman has a look at where both sides stand on the issue. >> reporter: almost from the moment that train crashed in the darkness, the battle lines were growing bright. democrats saying this wreck would not have happened if funding for infrastructure and safety equipment were not political footballs. >> the republicans have been very much against amtrak for a very long time. >> reporter: and republicans furiously hitting back. >> listen, you know, they started this yesterday. it's all about funding. it's all about funding. well, obviously, it's not about funding. the train was going twice the speed limit. >> reporter: much of the democratic focus is on a safety system called positive train control, which was supposed to be installed in all am track routes by this year's end and won't be. but assessments by congressional researcher, railway experts and others have all suggested a delay was inevitable because of technological and logistical challenges, not budget issues.

>> it's shameless that we have some of our colleagues trying to exploit such tragedy like this for funding. we need to figure out the facts first and move forward. ♪ >> reporter: amtrak has been freighted with politics ever since it started as a giant industry for the rail problems. it's popular in new york city which leads the nation with 9.5 million passengers a year. the northeast corridoroverall sees far more folks using trains than planes. but that region is also one the of the bluest parts of the political map. meaning republicans all amtrak spending wasteful, democrats there can push back and count on voter support. >> my criticism is it reflects i recklessness by republicans and their budgets. >> anybody who knows amtrak knows it's been robbing peter to pay paul. >> reporter: and for many voters

in the vast red part of the america, amtrak is a longstanding symbol of what the government should spend less money on not more. rescue teams in colombia are scrambling to find nine miners believed to be trapped in a collapsed gold mine. six bodies have been recovered in the western town. workers who escaped said the power failed on wednesday, shutting down pumps that send water rushing in and trapping people inside. the country's mining agency said the gold mine was not licensed or registered. well, in iraq, isis has taken over government buildings from iraqi forces in ramadi. its big push for the key city started on thursday. and friday's fighting left at least 47 iraqi security forces and more than two dozen civilians dead. ramadi is important for both sides, because it is a large city, quite close to baghdad about 78 miles or 126 kilometers

away. to get more perspective to this, i want to get to gemana, she's live via skype. what's the very latest from the ground? >> atika, we're trying to get a clearer picture of what is going on right now, the latest of what we're hearing from officials, the governor said the city has not fallen yet. he said the situation is very dire there. this is the latest offensive launched by isis that began on thursday, as you mentioned into friday also. we've seen them take over something that they have been trying to gain control over for months now. that provincial government headquarters, the government complex in the center of ramadi. very symbolic that they managed to finally take control of what used to be the nerve center of

anbar province and ramadi, raising the isis flag there. for months now, push after push, with isis trying to take control of that provincial capital as you mentioned. a key city. the desert, that sunni heartland that borders jordan, saudi arabia and syria. and also baghdad is very important for isis. it controls the majority of that province. this is where we saw isis first immerge in iraq, back last year. in january, before their major push into northern iraq. so, is this very important. they have been trying to consolidate and tighten their grip on the territory that they control. stretching all the way from the turkish syrian border to the outskirts of baghdad. taking over ramadi, it does seem at this point in time that it's

a time and until that happens is this a great gain for isis. a major blow, atika, for the iraqi government that has been tried to last month's launching and offensive to try and take back anbar province. a very complex situation there, after it announceded a victory north of baghdad in the city of that the key. they took over that city. but here, the challenges are very, very different. and of course, the u.s. air strikes intensify yesterday, also, the iraqi forces, the government saying they're sending elite troops into al anbar. a very tense situation unfolding. >> that's cnn's jomana karadsheh reporting. >> thousands of people in burundi are running for their lives. the latest on the amendmented

coup in burundi. >> and why some say kim jong-un may be losing his grip on power. you're watching cnn. that's going to go right in your glove. ohhh. oh. see that? great job. ok, now let's get ready for the ball... here it comes... here you go. good catch. perfect! alright now for the best part. let's see your pour. ohhh...let's get those in the bowl. these are way too good to waste, right? oh, yea. let's go for it... around the bowl and...

the president of burundi says peace has been restored in the african nation after chaos erupted this week. several military leaders attempted a coup on wednesday following weeks of protests. all the violence has forced more than 100,000 people to flee the country. that's according to the united nations. for more details, i want to bring in robin creel who is live with us in burundi. robin, i know you've been following this for some time now. tell me, who exactly is in control in burundi. >> all indications is that the president has ruled burundi for the past ten years since 2005 is firmly ensconced in control. he gave an address on the nation, on the state broadcaster, where he said that burundi was at peace.

he thanked beruineddyes for their attempts. and he said the borders have been reopened, they were shut during the sort of 48 hours of turmoil when the president left the country in burundi, and a major general in his army, the former head of intelligence declared that the president was being dismissed and a military coup d'etat was emerging. what started off as peaceful demonstrations by opposition parties and over the current president aziz's bid to run for a conversational third term in office descended into bloody street violence.

police fired tear gas and in turn they became the targets. there are reports that several protesters were killed and five police officers died as well. this woman was one of the lucky ones later rescued by her former officers. all the while, the military, seemingly sympathetic by both side of the fighting, tried to keep the peace. but on wednesday, the military became the center of the unrest. when major general declared the burundi military no longer declared the president. >> translator: president pierre aziz has been dismissed. >> reporter: the announcement was made when he was out of the

country in a summit in tanzania. they were met with jubilant crowds. demonstrators who believed the president's decision to run for office and extend his ten-year rule violates the constitution. and a deal that ended the bloody civil war. but massive firefighters rocked sunday night. soldiers pored out of their bear troux regain part of the city. and by friday, an announcement that the president was back in the country and in charge. most of the coup leaders are under arrest facing trial in a military court. but as the president settles back in office there are questions whether he'll continue his bid for a third term in office. and concerns that he will use the failed coup as an excuse to

crack down on further descent. meanwhile, the u.s. has warned of an impending refugee crisis. tens of thousands have fled to rwanda and the congo. for burundi and its people, much remains uncertain. we also understand that a number of evacuations are also under way of nongovernment organizations and the u.s. embassy saying they're sending family member, nonemergency, nonessential staff, just outside of the country, until it cools down. atika, back to you. >> thank you very much, robyn kriel in nairobi, kenya. egypt's morsi will learn his fate in a case. and there's the possibility that he will get the death penalty if

convicted. can you walk us through the charges, ian? he really has faced a number of court hearings, but this one it appears, could even result in the death penalty. you can explain to us what's happened? >> reporter: that's right, atika. there's actually five separate cases against the former president mohamed morsi. he's already been found guilty on one which involved the deaths of protesters, outside of the presidential palace while he was in power. he got 20 years for that. there's two cases, same judge. the first is the jailbreak case that happened in 2011. the government is saying 128 defendants were involved. that was a total of 20,000 people. the other and more serious case is this espionage case. this is a list of charges involved. including spying with a foreign organization outside of egypt.

committing terrorist acts inside egypt. disclosing classified defense to a foreign country, funding terrorism and military training to achieve the objectives of the national brotherhood organization. these are very serious charges that could potentially lead to the death sentence. now, there has been a lot of accusations that morsi couldn't get a fair trial here. groups have said, his lawyers have said he couldn't get enough access. they're questioning the procedures. the brotherhood has unsurprisingly called this a farce. but the government is very adamant about these charges, and they are moving forward. and really the question today isn't is whether or not he is innocent or guilty. i think a lot of people are expecting him to be found guilty. the question is what will that verdict be. will he get the death penalty, even if the judge does hand down that sort of sentence, there's still a lengthy appeals process

he has. at least two other appeals after this and also with this death sentence. it isn't just up to the judge. it will go to the grand muthy, he will have a say. ian is live outside that courthouse in egypt. well, finally, some rain in southern california in the united states yesterday. our derek van dam is standing by the international weather center with the details. i know they've been so concerned about this drought for so long, tell us about this situation at the moment. >> hi, atika. just to give you an idea of the longstanding nature of this drought, it took this young boy from dana point, california, 22 months, until he saw his first rainfall. it's a nice opportunity for mom catching father and baby boy enjoying the first rain drops. this is the storm over the western half of the united states.

that's the rainfall that provided that. they had to reroute flights. the eastern half of the united states looking wet as well. lots of eyes on the baltimore, maryland for the 140th annual preakness stakes horse racing event. and this storm system over the western half of the united states is also unfortunately going to set the stage for another round of severe weather. we have a slight to moderate risk of tornadoes some of which can be strong. from oklahoma and texas that would be the central plains states of the united states. we're going to leave you with a bit of a tear jjerker moment. we have had the birth of a baby beluga whale in atlanta taking its first breaths this sunday. shortly after that birth, the female calf swam to the surface with the aid of his mother and actually took his first breath

which is an important milestone. i just love mother nature at its finest, with the baby calf enjoying that first home. atika, the best part about this, this birth took place on mother's day. >> that is a very good thing. yeah. >> thank you so much, eric van dam for us at the international weather center. well, in asia now, a dire station, thousands of migrants trapped at sea with no place to land and suffering from dehydration and hunger. we'll have the latest on what's happening in southeast asia, coming up next.
