humanity... only on al jazeera america my speech is not intended to show any disrespect to president obama. >> washington and israel play down tensions surrounding prime minister benjamin netanyahu's controversial visit to the u.s. back at the negotiating table. peace talks between yemen's political factions resume. u.s. secretary of state

urges moscow and pro russia rebels to honor a cease fire in eastern ukraine or face the consequences. >> and we'll hear from a man once behind bars at guantanamo bay now struggling to adjust to a new life in uruguay. good to have you with us. benjamin netanyahu insists relations with the united states are strong despite a controversial speech planned for tuesday. he's visiting where he's giving a speech at a conference for a major israeli lobby. tuesday he'll address the u.s. congress which is upset the administrationset with the administration of barack obama. >> israel and the united states will continue to stand together because america and israel are

more than friends. we're like a family. we're practically -- now disagreements in the family are always uncomfortable. but we must always remember that we are family. [applause] [applause]. >> rooted in a common heritage, upholding common values sharing a common destiny, and that's the message i came to tell you today. our alliance is sound. our friendship is strong. and with your efforts, it will get even stronger in the years to come. >> let's go to washington d.c. patty, sounds to me like prime minister netanyahu and president obama are really stressing the depth of the relationship between the two countries but i still get the feeling the white house is not happy. >>reporter: and you would be

right. of course we're hearing from the president. he talks about the unbreakable bond with israel, the billions the u.s. has given to israel. and he says that this is basically not going to be destructive to the relationship over the long term. he calls it a distraction. but for the first time we are hearing more of his objections. in an interview he said it's the content of the speech that troubles him. and he reminded the prime minister and the audience watching that the president, the executive branch controls foreign policy in this country. here's what he had to say about that. >> i think those who offered the invitation and some of the those who said this is the right thing to do it's worth asking them whether when george w. bush had initiated the war in iraq and democrats were controlling congress if they had invited, let's say, the president of france to appear before congress to criticize or to air those

disagreements. i think most people would say, well, that wouldn't be the right thing to do. i guarantee you that some of the same people who are cheer leading now would have suggested that it was the right thing to do. i don't think it's permanently destructive. i think that it is a distraction from what should be our focus and our focus should be how do we stop iran from getting a nuclear weapon. >> patty, netanyahu has said that he's not intended to make this a partisan u.s. issue yet his visit has divided both parties. >>reporter: it has. dozens of democrats have said they will not attend the tend the speech although republicans are saying they'll put seat fillers there so it doesn't look bad for the prime minister. i think we are starting to see that. i want to point out a change in tact from the obama administration. for the first time, he laid out details of what they're negotiating with iran because

they're very concerned that the prime minister was going to cherry pick information to try and make the deal sound bad. so here's what we learned from the president in this interview. he said the deal is going to span double digits more than ten years. he talked about the goal being one year for break through. what does that mean? it basically means from the time the u.s. and the west discovered iran if they chose to develop a nuclear weapon it would take them a year to get to that capability. the bottom line is this. the prime minister says no enrichment. no enrichment for iran. that's what he wants. the white house has said that would not happen because iran would never agree to that just because of sanctions or the threat of military force. so tuesday netanyahu is going to congress where he has strength to try to make that claim that congress needs to get involved. congress is thinking about passing a bill saying they get the final say on any deal and the white house has said that's not going to happen. they're going to veto it.

they feel they can make this deal with the p 5 plus 1 and iran and they don't have to consult congress. that's what's happening behind the scenes. >> patty, thank you very

much. in times of iran's stance within the region we're getting reports today that there has been an iranian general who's been working with the iraqis to fight isis. is iran changing its focus and emphasis in the region as it has its changing relationship with the u.s. and the p 5 plus 1 >> no i think it's important not to become confused on this issue. the iranians are always going to pursue their own interests in the arab world, and that's completely irrelevant of any sort of nuclear agreement. however, when it comes to isis this is where the united states and the iranians are compatible and coincide. so if the iranians are fighting

isis which they are and are very much against, this doesn't mean it's changed its policies. it's doing what it sees as its interest in the middle east which also happens to be in the interest of the united states. so i think there's some of the confusion among those who really want a deal signed that somehow this is going to also alter iran's behavior in other ways and that's absolutely not the case. primarily because president rohani might be in charge of the nuclear fall but he's not in charge of iran's regional policies in the arab world. >> i want to take you back to what patty was saying about the fact that the u.s. special executive has said it will veto any attempt to increase sanctions on iran. who do you think prime minister netanyahu is making this speech for? the wider global audience?

the elections in israel, a domestic audience? >> it's for many audiences. so first it's for the domestic audience here in the united states. he's hoping that there will be enough pressure on congress so that congress will go ahead and try to pose more sanctions on iran and also block a nuclear deal. he's also appealing to his own constituency back in israel because elections are coming up. and he's appealing to people i think, in the middle east because he wants to show that israel is not a pushover. that the israelis are not going to agree to basically reconcile as he sees it with a country that hells is out for israel's destruction. so he's appealing to many audiences, but particularly to congress because he's hoping that there will be so much domestic pressure in the united states that the obama

administration will have to change its position on the negotiations and also will have to change its position on sanctions because, of course while these negotiations are going on it's not wise at all for the united states to pass more sanctions on iran if washington wants the iranians to cooperate. >> thanks very much for being with us indeed. the u.n.'s special advisor on yemen says all political parties are returning to the negotiating table. previous talks broke down when some protested over policies including the detention of the entire yemeni cabinet. here's more from aden. >>reporter: just the fact that all the parties have agreed to go back to the negotiation table may be a break in some respect but tonight's talks are not about the usual issues that all

sides have been discussing but rather about procedural things such as where to move the talks. president hadi has been demanding the talks be moved to a safer place where everybody can attend. some of the parties are opposed are making the same request and setting it to a precondition to resume the talks. now they are around the table to discuss this very issue and also the second issue being discussed is who represents president hadi. actually all the parties opposed say they speak in the name of president hadi but he needs a special representative to those

talks. houthi. following a meeting with the u.n. envoy to libya, they will meet for talks only if recognized as the sole government. it suspended talks in tripoli last week after suicide bombings. iraq's army backed by shia militia has launched a large scale military action to recapture the city of tikrit. it's been under the control of isil since june. here's that report. >>reporter: the assault, iraqi forces have already recaptured towns in this northern province. from the islamic state of iraq

the pride is tikrit. it's the birth place of saddam hussein and the heartland of the sunni muslim community. >> we will crush isil all over tikrit. >>reporter: the city was seized by the islamic state of iraq during a blitz attack last summer. >> today we launched this offensive to liberate the people of the province and that will include -- tikrit and all the other areas. this is a campaign to cleanse and liberate them from isil. >>reporter: a force of around 20,000 backed by fighter jets and helicopters has stormed tikrit. shia militia and 2,000 sunni tribal fighters have joined this massive operation. but there's a fear that the

largely shia-led attack could unfairly target sunnis in the region. returning to parliament, sunni politicians say threats have been made against people living inside the province. the army has recaptured a town. this video from iranian state tv is set to show the offensive. the commander of the iran elite revolutionary guard is heavily involved. tikrit is the biggest challenge so far for iraq's military. it's also a test as the country prepares to take back mosul in the coming months. the stronghold of isil in iraq. >> isil has had considerable military success but it appears to be on the defensive after months of air strikes by the

u.s.-led coalition. here's a look at the latest push to regain the require. >>reporter: isil started making -- declaring a caliphate. that same month the group captured mosul backed by other sunni groups. isil's siege of mount sinjar where tens of thousands of yazidis were stranded. more recently kurdish peshmerga have been making advances against isil. a coordinated mission to retake mosul will probably begin in april or may although the u.s. has indicated they may not be

ready by then but they first need to recapture the city of tikrit because of its strategic location of the north-south supply route from baghdad. we should not forget previous attempts to take tikrit have failed and there's likely to be strong resistance there at the very least two people killed and nine others injured in cairo. the bomb was hiddenen underneath a parked car. a group calling itself revolutionary punishment reportedly claims responsibility for the attack straight ahead, tensions power struggles, and mistrust between syria's rebel groups causes one of them to disband.

>> john kerry warned of further conventions if the kremlin and pro russian separatists fail to fully implement the cease fire. a fragile truce is holding in the east of the country where fighting has killed more than 6,000 people in less than a year. >>reporter: at her hotel in geneva, another round of talks. >> he's meeting with mr. kerry and said the minsk agreement was having a positive impact. >> the cease fire is taking hold.

heavy weapons are being pulled back. >>reporter: but john kerry said the minsk agreement was being selectively implemented. >> if there continue to be these broad swaths of noncompliance or there continues to be a cherry picking as to where heavy equipment will be moved back from without knowing where it's been moved to then there would be inevitably further consequences that will place added strain on russia's already troubled economy. >>reporter: it's one of several places where fighting continued after the minsk agreement. john kerry was critical of what he called a lack of clarity in the agreement. the u.n.'s latest report on eastern ukraine released here paints a bleak picture of the

humanitarian situation. it speaks of a merciless destruction of life and infrastructure. and that fighters and weapons are continuing to flow into eastern ukraine from russia. i asked the report's author about it. >> we've had, for example, serious allegations of people tortured. there was some media release that groups were at least threatening or possibly using hammers as well as surgery equipment to make people confess. this is very serious. >>reporter: who's doing this? >> well rebel groups. >>reporter: this is the ninth report the u.n. in geneva has released on human rights in ukraine that chart a growing death toll in a conflict russia and the west continue to interpret in very different ways.

kenneth roth is the executive director of human rights watch in new york and he says there's evidence ukraine and pro-russian forces are committing human rights abuses. >> in fact both of them are firing into populated areas. there have been reports from both sides of arbitrarily detaining people torturing them disappearing people. so there's plenty of abuse for the u.n. human rights council to focus on. what we need is dispassionate reporting on those abuses and pressure on both sides to stop them. not the partisanship they both carry nato's deputy secretary-general says russia is undermining peace in europe and creating fears in neighboring countries. and also violating its

international commitments. >>reporter: united against weapons of mass destruction, nato members and partners say they are eager to prevent the spread of nuclear weapons and arms trafficking. it's topped the agenda here in the capital of qatar. >> what's very concerning about ukraine is that the russian federation has taken a step backwards in its international commitments by violating the sovereignty of a neighbor by undermining all the basis of the post-war peace in europe. and that raises concerns as to whether they will sustain their commitments against the use of weapons of mass destruction. >>reporter: but this could be nato's biggest concern, isil fighters taking over more territory in syria and iraq and

spreading their ideology in the muslim world. the international military alliance said it's determined to take on isil. a coalition led by the u.s. is carrying out air strikes against the armed group. nato realized how important regional partners including qatar which has set up the committee for the prevention of weapons, the first body in the region responsible for ensuring chemical materials do not fall into the wrong hands. >> we play a significant role in international peace and security. in 2004, we created the convention of the prevention of chemical weapons. we train neighboring countries at international disarmorment conventions. >>reporter: the main goal is to limit nuclear weapons. a devicive issue here in the

middle east. if there's an agreement, iran would be allowed to develop nuclear energy for peaceful purposes. but the general sentiment in the region is that the whole middle east including israel should be free of weapons of mass destruction. >> libya no longer is a member of the chemical weapons convention. syria has -- so it's a better basis but you still have israel not being a member and egypt not being a member of the chemical weapons convention. >>reporter: but if syria and libya are seen as a success story for international peace by reannouncing their weapons of mass destruction ambitions, efforts continue to convince countries like north korea to reverse its 2003 decision to pull out from the nonproliferation treaty.

challenges nato wants its partners in this region to tackle aggressively to prevent further instability. northeast afghanistan is being hit with heavy snow and more than 40 avalanches a day. the military started air lifting supplies to some stranded villages but other areas are still cut off. nicole johnson reports from one of the worst hit areas. >>reporter: high above, the scale of the disaster unfolds. village after village covered in up to three meters of snow and it's still falling. communities are cut off from each other, roads have disappeared. everything is white. except for the houses the ones that haven't been lost.

the village of abdul la has survived but 30 people who lived in it did not. they were buried beyond the trees in two mass graves. we meet a 13-year-old boy who shows us around and points to the houses where people have died. >> the avalanche hit at midnight when everyone was sleeping. i was so scared. i heard a great noise. later i felt sad because it hit my friend's house and he died with all of his family. >>reporter: this little boy looks alone in the world. his mother and four sisters died when their bedroom crumbled underthe weight of the snow. in many ways this village is now one of the lucky ones. helicopters are able to land here and the main road has almost reached it. but there are still dozens of remotere remote villages in the mountains that the government simply can't get to. the weather has closed in.

helicopters can't reach it. >> the most important issue for us is the areas we haven't reached yet by road. we are trying to help them by air but the aid we are dropping is not enough for everyone. >>reporter: the government is giving cash payments of $1,800 to relatives of anyone who died in the snow storm. the oldest man in the village said he's seen avalanches before but never anything like this. recovery will take a long time. many people are still in shock. >> from midnight to 5:00 a.m. we worked hard to take the dead bodies out of dust and snow. people were so frightened you would think it was dooms day. there was no hope for life. we didn't think we would ever sit together again. >>reporter: here the snow has been cleared away to make room for two freshly dug graves. cousins, young boys. they died when the roof

collapsed. the valley is bracing for many more funerals before the snow melts. nicole johnston al jazeera. still to come on the program, tensions build in the korean peninsula as south korea begins its annual military drills with the united states. 60% of africa's sex workers are hiv positive. now there's a controversial push to change that and i'm here with the sport that's lifting the pacific in sight of an olympic medal.

>> protestors are gathering... >> there's an air of tension right now... >> the crowd chanting for democracy...

"stolen sisters", an "america tonight" special report. tomorrow, 10:00 eastern. only on al jazeera america. barack obama calls the israeli prime minister's speech to congress a distraction to nuclear negotiations with iran. prime minister netanyahu's speech on tuesday was at the invitation of house republicans without obama's knowledge. the israeli leader insists

israel's relationship with the united states is still strong. >> u.s. advisor to yemen -- large scale military operation to recapture the city of tikrit. at least 20,000 soldiers and -- >> isil has released 21 christian hostages who were abducted in northeastern syria but the group is still holding more than 200 christians. some of these freed were welcomed at a church. a coalition of syrian rebels has disbanded after days of

fighting. the hazm movement has joined another front. it said the infighting was distracting the opposition from battling the syrian regime. the group had received weapons and training from the united states and qatar and beirut. >>reporter: they lost many men in the fight and the hazm movement has collapsed. they died fighting al quaeda's affiliates in syria in the western countryside of aleppo. a few -- accusing it of kidnapping and killing its fighters. it is a charge the group denies but they have still decided to disband. in a statement, the syrian military began to advance on several front lines in recent days because of the opposition's infighting. as long as hazm remains, it would be a target and a distraction for the opposition.

the fighting in aleppo was not the first confrontation. a few months ago it was -- it was the first group to receive sophisticated weapons from the u.s. but its links with the west only earned it enemies on the ground. >> the fact that they have the movement no longer exists is a set back to the u.s. plans to arm and train a rebel force but this is not the only obstacle that the obama administration faces. for the opposition, the priority should be fighting the government. syrians in opposition controlled areas are worried. the rebel infighting coincides with government efforts to control aleppo city and cut off opposition supply lines to turkey. >> we called on the rebels to stop fighting each other. nusra should go to the front lines and fight the regime

instead. we are being attacked by militias from iran and other shias. they are trying to lay siege to aleppo. >>reporter: hazm was one of the few rebel groups that the united states trusted in syria. some of its members may still join. but it will face opposition not just from the government and isil but from within rebel ranks. new leaked recordings allegedly reveal how egypt's military and president el-sisi discussed ways to take advantage of a low-cost housing project. the recordings were made when el-sisi was defense minister. he's apparently talking about taking a commission from a project to build residential units for young people. it allegedly implicates the

united arab emirates in being involved. political players could have leaked the conversation to embarrass the government. >> what's asking is, of course the timing. why these leaks come to the surface right now and at this point in time. the uae was a very important player in propping up the egyptian economy ever since the military and the movement of general el-sisi to the presidency. the interesting questions now are who leaked it and what is the objective. if you look at the context, there are still parliamentary elections that need to take place in egypt and they are due to take place this month although last week it appeared that there was a court ruling

that may cause it to be postponed. so it's quite possible that certain political players in egypt have an interest in making this kind of leak coming into the open right now to embarrass the government >> north korea says it's set to make merciless strikes against it enemies. it made the strikes after launching two missiles in defiance of u.n. sanctions. they flew about 500 kilometers before falling into the ocean. it's seen as a protest between joint military drills between south korea and the united states. >>reporter: when two countries are technically still at war, any show of force makes people nervous. every year south korea and the u.s. show off their fire power in joint drills. every year north korea responds. this time, it fired two short range missiles before the south

korean drills even began. >> this is a deliberate provokation seen as an armed protest. our military will react formally and strongly so north korea will regret bitterly. >>reporter: afraid things could escalate, a group of peace activists gathered within hours. they're part of a south korean organization campaigning for both koreas to be reunited as one country. >> we are against all military actions taking place in the korean peninsula. if north korea retaliates retaliates retaliates, war will be a reality. >>reporter: but we've heard all this before and even an analyst from the international crisis group isn't worried. >> he's told them to be ready for war but if you look at the text, it's all in the context of

deterrents the nittys -- >>reporter: in other words this may just be another case of posturing. however, history has taught us that the standoff on the korean peninsula is unpredictable. cuba's former leader fidel castro has met five cuban spies released from a u.s. prison. they were released as part of a prisoner swam with the united states. it the five intelligence agents are honored as heros of the republic for spying on anti-castro extremist groups in the united states and uruguay -- it looked like a new start for the men but three months later, they're struggling to adapt. we spoke to some of them.

>>reporter: after more than 12 years detained at the u.s. guantanamo bay, a chef from tunisia was delighted to be offered a new home in uruguay. it was a country he knew little about but knew it was a long way from the life he'd been living. as a prisoner never charged with any crime but with no home to return to. >> i want to stay in uruguay and rebuild my life. if i didn't what would i do? >> i have a passport or papers. i asked for the americans to send me back to tunisia but they refused. >>reporter: he'd like to open a restaurant serving arabic food. he would also like to be reunited with his mother. >> when we were -- uruguayen

authorities made my promises but they have not been fulfilled. >>reporter: one of the other men has moved out of the house donated by the uruguay trade union movement and now live in a nearby hotel. he says it was too crowded. their costs are covered by the government here and the united nations refugee agency. their resettlement was a priority for the president of uruguay who just left office. his successor is less enthusiastic about the project. there was plenty they would like to have said. none was willing to discuss their time in guantanamo, at least not yet. but the most important message is that they want to be reunited with their families as soon as possible. he's desperate to be reunited with his family. he's been to to argentina to

talk about their polite >> only god knows the future. >>reporter: it's a future in a foreign land that's no longer sure it still wants them and where they're still trying to learn the language. freedom is fraught with difficulties. a fire swept through manila in the philippines. some have accused firefighters of being slow to tackle the blaze. children in liberia are back in the classroom after several months away from school. liberia was worst hit by the ebola outbreak.

use but some police use them as proof of criminality and brings their use to an abrupt end. some fear carrying condoms because that means you're almost saying i'm a prostitute and risk being arrested. >>reporter: she didn't report being raped to the police because she didn't think they'd take her seriously. she's hiv positive too but says the government's hiv prevention program due to be launched this year won't work. >> the health program will only work once sex work has been decriminalize because we're too afraid of the stigma and discrimination from nurses. >>reporter: there is some precedent. south africa is a largely conservative society but has taken a more liberal stance than other african countries on several issues both abortion

and same-sex marriage is legal here. the deputy minister of justice accepts the current situation doesn't work. >> it's happening. that criminalization has not stopped it. there's a variety of factors that need to be looked at and we'll ultimately have to do what's right. >>reporter: many people may take some convincing but south africa's status as having the highest rate of hiv in the world may be the deciding factor. that alone may convince the government the only answer is to decriminalize the oldest profession in the world. still ahead sensors take center stage at barcelona's annual technology conference. we'll tell you how they're being used.

that goes into determining their final score. they're used in smart vending machines like this to tell the vendor which products are selling and which need to be

smell a medal. it would be just the second time one of the islands had won any olympic medal. only 17 months of lifting to go. the prize for african leadership has been awarded to the outgoing president of -- he won the $5 million prize. it's only been given out four times in eight years. it recognizes democratic elected leaders who governed well and left office once their term ended. >>reporter: his prized achievement in african leadership has only been one

four times since 2007. he says that doesn't mean africa is doing badly. >> i accept we have some challenges in africa. i don't have issues. but we are moving forward. 95% of african people today live under better governed societies than ten years ago. it's not perfect. and it's not by wide margin. but it is a movement -- in many parts of africa. >> there are worrying times. some african leaders look like they want to hang on to powers so they can have a third term in office. some of those countries include togo. >>reporter: some say perhaps the

term leader should be defined. >> we have a special kind of press prestige to political leadership. >>reporter: one incentive is prize money of $5 million paid over ten years followed by $200,000 a year for life. but some wonder if that's enough motivation for some of africa's current crop of leaders. just before we go i wanted to show you some live pictures out of montgomery in pennsylvania. this is apparently a major fire a four-alarm fire at a sheet metal plant in montgomery county in pennsylvania. we've seen pictures of a lot of emergency vehicles. we'll have more on that in the news hour which is coming up on al jazeera in a couple of minutes. bye for now.
