rest of the day's news, go to the website, aljazeera.com. there in particular we are concentrating on our top story, the release of the 10 u.s. sailors by the iranians, at aljazeera.com. iran releases ten american sailors, the pentagon investigating why their naval votes entered iranian waters. >> i don't want to just talk about next year, i want to focus on the next five years, and beyond. >> president obama's final state of the union. and back to california, the nfl's rams get the okay to turn to the place they called home

for decades. ♪ this is al jazeera america live from new york city. i'm stephanie sy. the pentagon is praising the timely release of ten u.s. sailors handed over by iran. the boats were en route to bahrain from kuwait when they entered iranian waters. iran accused the boats of trespassing. >> translator: certainly the presence of the u.s. in the gulf has never been next. >> reporter: but the mechanic says one of the boats had a mechanical failure. rosiland jordan has been following this story all morning. we are learning more about this release, including secretary of

state john kerry's role. >> reporter: that's right. we did know as of late on tuesday evening, secretary of state john kerry had spoken with the iranian foreign minister and directly appealed for the quick release of the ten sailors, nine men and one woman, who were on two patrol boats. as you noted, stephanie, they were headed from kuwait, south to bahrain, when app pair wently they had some sort of mechanical problem, and ended up landing at an island which is controlled by iran. there were suspensions voiced be i the iranian military that the u.s. sailors were up to no good. apparently the secretary of state made it plain that this was not the case that this was a situation where one of the two patrol boats had a mechanical problem, so after between 16 and 20 hours -- we're not really

sure how long the sailors were in iranian custody, they were handed back to the u.s. at about 3:47 am eastern time today. they are said to be in much better condition. they are going to be bebriefed. we did hear from the secretary of state who as we noted was very much involved in the release of these ten sailor, and i want to read a bit of his statement. now this is definitely can be read as a rebuttal as it were to some congressional republicans who were saying that the u.s. needed to play hardball about the situation. there was one u.s. senator who

suggested that the u.s. should probably take some sort of military action. of course that didn't happen. >> yeah, but it does come at a particularly delicate moment, just as the nuclear deal is to be put formally into place a week after those missile fly-byes. would there be political repercussions? >> reporter: analysts are suggesting first that in iran, the fact that the sailors were taken into custody and detained might have been an effort by hard liners in the iranian political structure who have been opposed to this deal, that basically prevents iran from ever developing nuclear weapons. now as you saw there was some really tough language, some potentially inflammatory language coming from the iranian military on tuesday about what the sailors were doing and where they were going.

from the u.s. you can probably expect congressional republicans to be critical about how this was resolved. >> and again, they have launched an investigation this morning. rosiland jordan live for us in washington. thank you. iran is on the docket today at the supreme court. the justices are hearing a case over how to collect $2 billion frozen in iranian accounts here in the u.s. the suit was brought by the families of marines killed in beirut in 1983. the high court has to decide whether construction acted unconstitutionally when it passed a law saying the families should get that money. and iran was part of the participate's state of the union address last night. but the white house has yet to comment about the release of those sailors. mike viqueira is live in the nation's capitol as well this morning. mike, good morning. what has been the reaction from

both sides of the aisle to the president's address last night? >> reporter: it's about what you would expect, not withstanding the plea for more bipartisanship, saying he failed to fix washington as he campaigned for on change. republicans dug inasmuch as ever a schism on the right in the wake of the response from nikki haley, but it was a speech that would only be given by a president that is in his final term. a sworning, even ridiculing republicans at some point, and urging voters to help him change the tone in washington. >> the president of the united states. >> reporter: president obama didn't just taught his record he dared republicans to dispute it. on the economy. >> anyone claiming that

america's economy is in decline is peddling fixture. >> reporter: on who is to blame for the recession. >> reporter: food stamp recipients did not cause the financial crisis. recklessness on wall street did. >> reporter: it was the same on climate change and the fight against isil. mr. obama using his last state of the union to deliver a in your face address directed at republicans. his sworn extended to the campaign trail and senator ted cruz, the republican who called for american bombers to make the syrian sand slow. >> and our answer needs to be more than tough talk. >> reporter: and he hit back at republicans like donald trump who wanted to label the battle on isil as one on islamic terrorism. >> we don't need to echo the lie that isil is somehow representative of one of the world's largest religions nch

>> reporter: there were echos of that criticism in the republican response. as nikki haley called out the most strident voices in her own party. >> during anxious times it can be tempting to follow the siren call of the angriest voices. we must resist that temptation. >> reporter: but with the first vote set to be cast in two weeks, haley made the case for a republican in the white house. >> if we held the white house taxes would be lower for working families and we would put the breaks on one away spending and debt. >> reporter: so a lot of tradition around the state of the union every year, stephanie, as you know, and one more tradition is presidents usually hit the road to try to strike the same message as they did in the night of the big speech. today he heads to omaha, nebraska, he has a discussion and then a speech, the focus to be at least in part on

education. he spends the night away from the white house, we'll be in baton rouge, and then on the 20th he wants to taught the recovery of the auto industry and will head to detroit for the auto show. >> nikki haley, the opposing party's response, it usually doesn't gain as much attention. did she help or hurt herself? >> reporter: the only notable thing you can do is hurt yourself in the republican response. people look at what marco rubio did in his untimely grab for a bottle of water. bobby jindal's speech didn't go over well. i think nikki haley cast her lot

with the establishment. you heard in the spot that i reported just a moment ago, she decried the loud voices within the republican party, a clear allusion to donald trump. she also said that the g.o.p. has contributed to the erosion of public trust in leadership around the country. many voices on the right in the aftermath of that speech are angry, saying that nikki haley has betrayed conservative values, however, main stream voices such as the rnchave cheered nikki haley. >> thanks, mike. pakistani officials are investigating a suicide attack near a polio evacuation center. at least 14 people died. 12 of the dead were police. the bombing happened shortly before vaccination teams were to

be dispatched as part of an immunization campaign. isil has claimed responsible for an pakistani attack. a suicide bomber was killed during the attack. two other gunmen were later killed in a gun battle with security forces. and turkey says one person is now in custody in connection with tuesday's attack in istanbul. at least ten people died most of them germans, now ankara is trying to reassure its people. >> translator: turkey is exerting a lot of effort to fight terrorism and turkey is adopting a decisive stance against terrorism, and terrorists. during the recent attack and even one week before this attack, we have stopped 220

persons being affiliated to isil. >> despite the assurances, this is a look live at a memorial, a makeshift memorial that has been built around the square that was attacked in istanbul. our correspondent has more on the person who carried it out. >> reporter: we're not hearing a lot of detail, but it seems they are directly connected according to the turkish authorities with the suicide bomber and the attack was made here in istanbul. it's one of what we believe so far -- 68 people to be detained across seven provinces that have been involved in these raids. we're hearing there are also three russians amongst that figure. we have been told by a turkish news agency here that the turkish -- sorry the russians had some sort of documents and implicated them in providing

logistics for isil, we don't know if it again has anything to do with the bombing that took place here. really across the country they have hit areas and people they believe are possibly a danger to turkish society. they are also were saying, the turkish interior minister was saying that they have since -- the troubles with isil began, detained 3,000 people in all, and 800 of those are now in jail. i should make the distinction between they detain people that doesn't mean they are arrested. they have to go to court for that, and a judge deems whether they should be put in prison when investigations continue. in the past six months alone, isil attacks in turkey have killed at least 145 people. in cameroon at least two people are dead after two female suicide bombers attacked a mosque.
