>> donald trump and hillary clinton pull further ahead in the white house race, but their challengers aren't done yet. you're watching al jazeera live from our headquarters in doha. also coming up, jordanian security forces kill seven near the syrian border. >> gulf countries declare hezbollah a terrorist organization. i'm at the moscow museum of

cosmonautics, experiencing a little bit of what the man who just returned to earth experienced after nearly a year in space. u.s. presidential front runners donald trump and hillary clinton are increasingly setting their sights on novembered general election after big wins in the latest round of primary votes. super tuesday saw both pull further ahead in the race to secure the rival party's nominations for the white house. we have special coverage out of washington, d.c. >> it is 1400g.m.t., 9:00 in the morning here in the u.s. capitol. the u.s. has weak in up to the news that it looks like donald trump and hillary clinton will be going head-to-head for what is argue glee the most important leadership role in the world. mostly in the south, trump won in alabama, georgia, tennessee,

vermont and virginia. ted cruz won in three, including his home state, the accident, marco rubio claimed just one state, minnesota. it was a successful night for hillary clinton. she won overwhelmingly in the south with support from hispanic and black voters. like trump, she took seven states. massachusetts, the accident, arkansas, texas, and georgia. although trump can still be beaten it is looking increasingly unlikely. those all important delegates we keep talking about are crucial here. who are these powerful people? they are elected party leaders, they are party activists who run for positions and they are government officials.

in addition, the average american can also apply for this all important position. these delegates will eventually vote for their candidates at the national convention. what this means is, and that is key, it is not the number of states won that determines the winner, it is the total number of delegates they manage to rack up. all right, now that super tuesday is over, one of the next major prizes is ohio. since 1896, the state has only failed twice to vote for the candidate who eventually became president. on march 15, ohio homicide its primary election. the results are expected to narrow the field of candidates, as john hendren explains. >> if you want to become an american president, history says you have to win here first. >> mr. donald j. trump! >> every serious candidate has always been here and will come again and again. >> i love ohio.

>> said a microcosm of the country. you have every single part of the country represented right here. >> the state mix of urban and rural, wealthy and poor, black and white makes it known for picking presidents more than any other. >> now is probably one of a dozen of battle ground states for the presidency. >> only a dozen. >> out of 50 states, there are only 12 where there is a real contest, that's been ohio for years and years and years. demographically, it mirrors the country. >> in the general election, that mirror has long caste a strikingly accurate reflection of what happens in the nation when all the votes are cast. >> ohio has become the gateway to the white house. every single president since 1964, johnson, nixon, carter, the elder bush, the young herb bush and obama all had to win here first. the state votes within 1.3 percentage points of the national vote tally in the

presidency. >> this year marks a turning point in ohio and the nation. for the first time, millennials, born after 1980 will match baby boomers as a share of the electorate. >> we've grown up in a time where there's been a lot of economic hardship. >> that goes for young democrats. >> i can afford a republican president to be in office, i am white, male, straight and middle class but for a lot of people in marginalized communities, they cannot afford four more years of represent. >> the rather than i think it should be bernie sanders is because of the consistent 40 years of consistent progressive policies. >> millennials like me are invested in protecting gay rights, protecting the ability to marry the one you love. >> i'm for donald trump, because i want to make america great again, and build the wall, build that wall, donald.

>> because of how it is. >> thank you. >> all of the candidates will campaign here aggressively. they know if their dream of the white house is to become a reality, they must win here. al jazeera, columbus, ohio. i'll be back in an hour or so with much more on this fascinating race for the white house, but right now, let's hand you back to doreen. to the rest of the day's news, a tsunami warning has been issued in indonesia after an earthquake struck off as you metra. it was felt strongly and many of them ran for their homes. we are in jakarta. tell us more about the situation there. >> yes, a tsunami warning in five provines on the island of sumatra, but the worst hit closest to the epicenter is west

sumatra, a city of 1 million people, is basically the one to watch. the reports coming from the city, they haven't seen any damage so far and also no tsunami. there is an island chain, there's three islands there and those islands have been hit before in 2010 by a tsunami and hundreds of people died five years ago. at the moment, there's no contact with these islands, because the phone lines are not working right now, but we have to say that the people there have quite an experience dealing with earthquakes. they happen very regular in this area, and they always have the experience of just running to high ground if this happens. this is what we see in the coast and also in the city, people

don't panic anymore. they have the importance and they just go to the higher ground. of course, they are quite shocked by the strength of the earthquake, but so far, no tsunami yet and we are waiting for the lifting of the warning in the next hour. >> thank you for that update from jakarta. jordanian security forces killed seven men targeting fighters in the city of idlib. they were hold up inside a palestinian refugee camp in the heart of the city. the jordanian government said they had links to isil. a police officer was also shot dead in an exchange of gunfire. our correspondent is in. >> man. >> jordanians are describing this as a successful attempt to

foil an attack on jordanians and military installations. this centered in the city where special forces and police backed by attack helicopters closed in on a residential compound in a palestinian refugee camp. seven fighters were killed, some wearing explosive belts according to official media. a police officer was also killed and more than 30 people arrested. jordan has said that because of its proximity to syria and iraq and its general proximity to conflict in the region, it is at risk for serious threats from isil and sympathizers in jordan. these were described as outlaws by jordanian officials, indicating because it didn't say that they were a different nationality that they are in fact jordanian. this has been as well as a threat from the syrian conflict. very much homegrown threat here in jordan for many years.

>> the gulf cooperation council designated hezbollah as a terrorist organization. the move deepened a wrist with lebanon where hezbollah is a leading political power. in 2013, the g.c.c. imposed sanctions on hezbollah members in response to their intervention in syria's civil war. two weeks ago, saudi arabia announced it was cutting $4 billion in aid to lebanese security forces and i should travel warnings to the nation. on tuesday, hezbollah leader sharply criticized saws rain for the punitive measures and insisted that his shia group would remain in lebanon's coalition government. earlier, i spoke with a political analyst in beirut. he says he doesn't see an end to the conflict between hezbollah and saudi arabia. >> hezbollah is part of a coalition that is actually fighting a war on one side and there's another coalition fighting the war on the other

side, so, and the statement that came from hezbollah is very clear. every accused cause rain of sending those car bomb to beirut and rest of the area where there is loyalty to hezbollah. in the end, i think hezbollah declared that he wanted to end the regime of saudi arabia and that is a statement declared as the saudis actually are trying to destroy hezbollah wherever they can have or they have their hands on it. >> tensions are high in eastern iraq where isil killed 40 people during a suicide attack at a shia funeral monday. militias reiterated to leave the town immediately. since january, they have been carrying out reprisal attacks on

sunnies. five were killed and two kidnapped on monday. the u.s. led anti isil coalition carried out 21 airstrikes on key positions in iraq and syria. 14 were in iraq, focusing on mosul and fallujah. on the ground, shia militias launched an operation to try to dislodge isil fighters in the western desert. rebels attacked a city, five attackers died two after detonating suicide explosives. two civilians have been killed and 19 injured with that that number is expected to rise. no group that claimed responsibility for the blasts in afghanistan. >> according to an afghan government spokesman it took security forces 15 minutes to end this attack. it left five of the attackers

dead. one blew himself up in a car packed with explosives at the entrance to the security cordon leading to the indians consulate. one detonate his suicide vest and three others were shot dead by supreme court forces. they had made their way to a house from which they were trying to launch an attack but were overpowered and killed. it did leave civilian casualties, because this is very much a residential area. we're toldal few have been killed, many more injured, some children, one as young as one. the consulate are very much under the target of the taliban and extremist groups because they see the indian government as using afghanistan as a platform to destabilize their allies in pakistan, but this bombing is happening at a crucial time. it was hoped that taliban would attend very important talks in pakistan with the afghan

government, some kind of recourse to find a solution to this problem. the taliban is growing in strengths week by week, taking more area. of course this kind of attack on the indian consulate could be counterproductive. it could cause the afghan government to say when you're doing this, we cannot talk and that's the crucial point at the moment. >> still to come on the program, why business is booming for syrian refugees who put roots down on the border in turkey. >> syrians and iraqis are not the only people fleeing conflicts. by god if things calm

down tomorrow morning, i will return back to syria by the night. >> turkey offers syrians refuge and good business opportunities. for those that became successful, a return to syria requires starting every all over again. >> still in syria, 20 kurdish

y.p.g. fighters and 10 civilians have been killed fighting isil. the y.p.g. launched an offensive near the border with turn key. the attack was in retaliation for assaults by isil in syria's northern province over the weekend. >> macedonia has briefly opened its border to let refugees cross over from greece, but thousands still remain stranded on the greek macedonian border. the united nations is warning of a humanitarian crisis building, that's as refugees struggle with the cold weather. balkan countries put restrictions on the numbers crossing over to make their way to western europe. let's find out the situation for refugees that are still stuck. hodor. >> there are 9,000 to 10,000

refugees. it's very difficult to figure out how many there are simply because the system has broken down by which they were counting the people arriving here. as you mentioned, conditions are extremely difficult, the weather has turned. it's becoming cold and windy again and a storm is expected overnight. you can see behind me the amount of tents. we are on one side of the railroad track. on the other side, you will see that same scene stretching along the border. the biggest problem is the uncertainty people are facing, how long they will be waiting here. you mentioned that the border has opened briefly. during that brief time, only 170 people went through. if you do the math, this will take about 50 days just to get those ready here across the border into macedonia. the other issue, the restrictions, what kind of paperwork they need. there's all sorts of rumors going around the camp, because

people are not informed. actually, they do stop journalists asking if i have this passport, this paper, will i be able to get through. there are rumors that may be starting, people who come from certain area will not be allowed, so all this is certainly having a huge toll on all these people here. 54% are women and children and those are the ones who are suffering the most. i was talking to a woman earlier. she's a syrian occurred. her daughter has been very depressed and has stopped eating for the past two days simply because she didn't want her mother to stand in the cue to get food. that cue stretches for about 20s extremely long and that little girl thought it was very humiliating for her and for her mother. another one told me that she had a miscarriage in her tent just 24 hours ago and she didn't know how to explain that to her other children.

>> thank you very much for that update and for sharing some of the stories. hoe door has been hearing from refugees along the greek-mass den i can't border. many say they are being separated into different groups, adding to concerns that european governments are giving preferential treatment to people from iraq and syria. >> these are some of the african refugees stranded in athens. the majority of somalis fleeing the conflict in their country. they are not allowed to cross the border to the rest of europe, and now their whole world is justice inside athens. this two bedroom apartment is home to 30 of them. >> i can't leave athens. i feel trapped. i didn't cross through so many countries to lead this life. i don't know what to do if they don't allow to us cross the border. >> as the flow of migrants

increases, sympathy has dwindled. refugees from iraq and syria may get little. africans get none. >> the refugees may have been divided into two distinction classes with two different kinds of welcome. the hundreds of thousands of syria and iraq and the secondly, the much poorer and less educated men and women fleeing africa. >> it took her three years to reach her. they left by boat to yemen after she got injured in the head. she crossed libya, syria and turkey. the single mother have six unsuccessfully tried to cross the greek macedonian border three times since she arrived here four months ago. >> the segregation must stop. that's all we ask. we are all human beings. we should be treated equally. my country has been at war far

longer than syria. >> agencies warn that the refugees are now at a higher risk of being preyed upon. >> we want to see the people treated in a dignified way, providing safe ways for people to seek asylum. we stop what we see as a network of people being abused in order to do something that they have the right to do. >> at public parks across athens, migrants can be seen huddled together. it's the only thing they can do to while away the hours. they say their dreams have not died yet. at least they have plenty of time to think about their lives. al jazeera, athens, greece. northern france police in the port of calais are continuing to demolish the southern part of the refugee camp known os the jungle. police fired tear gas as people who refused to leave their makeshift homes.

france wants to move 1,000 refugees and migrants from the camp, but campaigners say it's closer to 3,500. authorities are accused of brutally evictimming migrants. israeli soldiers have shot dead two palestinian high school students in the settlement north of ramallah after an alleged stabbing incident. 186 palestinians and 28 israelis have been killed in violence in israel in the occupied territory since october. >> the u.s. released what appears to be a handwritten will of the late al-qaeda leader osama bin laden. in it, bin laden asked that the majority of his $29 million fortune be spent on continuing jihad. other documents were also released, including one that instructed one of his wives to be sure that her tooth filling didn't have a tracking device. bin laden was killed by u.s. special forces in 2011 in a raid on his compound in pakistan.

in new delhi, a high court granted bail to a student leader charged with sedition. he was arrested on february 12 after students held a rally against the man convicted for the 2013 attack on india's parliament. the arrest triggered large protests across the country. >> after a 340 day mission, nasa astronaut scott kelly returned safely to earth. he is the first astronaut to spend a year in space, helping take one giant leap to putting boots on that mars. we have this report. >> scott kelly and two others bid farewell and then closed the hatch on their time aboard the international space station. their 340 days in orbit are seen as a vital stepping down to a future mars mission.

>> interplanetary information will be how the human body holds up to micro gravity, weightlessness. we know from studies on the space station, that they go through bone loss and muscle mass loss to the tune of something like 1.5% of their bone mass each month. >> after their journey back to earth, the three safely landed in the snow why wilderness of kazakhstan. they were supposed to exit the capsule themselves like they'd have to after traveling to mars, but the debilitating effect were clear and the men too weak to do this. scott's body will be compared to his earth bond twin brother mark to analyze changes. for kelly, the u.s. astronaut with the most consecutive days

in space, any enthusiast will tell you the record belongs to a russian. >> we should say it's not the first such lengthy flight. in 1994, 1995, our com pat receipt set the world record of 437 days. that's almost enough time to fly to mars and back. he carried out many experiments and his work was very important. >> of course nothing actually replicates the experience of reentry. it's one of those things you have to do yours, but this simulator certainly shows how cramped it is inside this tiny capsule, the only thing keeping the men alive. it shows how the vacuum and extreme temperatures of space are just sent meters from their heads. >> museums like this and coverage of missions like this just returned to earth a testament to much excitement human space flight still generates and hopefully for

these children, there's a future visit to mars. >> you can read much more about that report that rory filed from moscow on our website, aljazeera.com. there call find the day's other top stories, everything we're covering at aljazeera.com. you. hillary clinton and donald trump both win big on super tuesday and begin sizing each other up for a november matchup. both sides try to sway the supreme court justice over a controversial texas abortion law. this is not a marketing issue. >> defending his decision, apple takes steps to avoid unlocking an iphone.
