attack on donald trump. we look at the challenges of protecting elephants in thailand where it is illegal to sell certain types of ivory good to you have your company. economic migrants are urged not to come to unit as europe tries to get a grip on the refuse gee crisis. that comes at 25,000 refugees and migrants remain trapped in greece as neighboring countries impose entry restrictions. 10,000 are stranded on the greek side of the macedonia border where tensions are flairing as police block their path towards western europe. 500 people have been allowed to pass since tuesday. on thursday a group of migrants laid down on the railway line in

protest. more from our correspondent. >> reporter: the living conditions in this makeshift camp are becoming more and more difficult simply because of the sheer volume of people that continue to arrive here hoping to make it through. now, there's an incredible amount of young children and i've seen some walking barefoot. there is uncertainty here and you have despair, anger and frustration. tempers flair a lot around the camp. you see people not able to contain their emotions any more. you see people who are saying maybe it will be less humiliating to go back to syria. at the crossing itself it is a complete chaos. greek authorities have tried to put some sort of order there, but people have also been waiting for days and they want to - they are eager to get as

quickly as possible across. only 500 passed over a period of 24 hours, but some of them have been pushed back. this has all to do with the new guidelines about the paperwork. the officers at the border know exactly what are the new regulations and refugees don't. now, one of the main issues is the registration paper that was given by the greek authorities when they first land on one of the islands. those are photocopied papers where the greek authorities add the name and then stamp. at this stage macedonians are not accepting that piece of paper and want it to be restamped again. so you have a very long queue of people going through that process the leaders of britain and france have met to discuss the ongoing refugee crisis and the looming referendum on the membership. from calais, here is paul brennan. >> reporter: a century ago france and britain fought

shoulder to shoulder around the month dern city. there was cameron and francois hollande starting their conference. the two men and their ministers got down to business, an agenda dominated by their bilateral position on refugee and security. the security threatened possibly by the referendum on membership >> translation: there will be consequences if the u.k. is to leave the e.u. there will be impacts on economic trade, on development. there will be consequences, especially in terms of people as well. >> reporter: there was progress in a promise that unaccompanied refugee children will be allowed to join relatives already in the u.k. but the headline british response was to promise more financial support so most

refugees stay on french soil >> we will invest an additional 70 million pounds in calais to assist the work of the french police. the money will go towards efforts to move people from the damps in-- camps in calais to other facilities in france and we will do joint works to return refugees to their home countries. the challenge is in the eastern mediterranean where we need to stop the people smugglers. >> reporter: the demolition of parts of the refugee camp in calais known as the jungle continues. undeterred by sporadic fires, the teams have flattened a large area of the camp. it has been a potent symbol of the crisis here in northern europe. a p clearance of large areas of it in the past couple of days by the authorities certainly sends a powerful message to those

refugees hoping to come here in the expectation of being able to reach the u.k. there are questions of whether throwing munno problem is a real solution >> it is not only a money issue, with-- throwing money is a real solution. >> it is not a money issue. it is a visa issue, a global picture of what countries what to do with people coming to our countries, are they refugees and do they have the right to be here in europe on that. >> reporter: that can only be addressed at the full european union summit on migration and refugees being convened next week electricity is slowly being restored to parts of syria after

state media reported a national wide blackout. authorities say full power will be restored by midnight local time, but the cause of the blackout isn't yet known. meanwhile, france and britain have called on the syrian government and allies including russia to stop attacking the opposition. this video purports to show russian air strikes on the syrian town just days after a cessation of hostilities came into effect. all signs in the-- sides in the collect accuse of each other of violating the truce since it came into force on saturday. amnesty international says russian jets carried out air strikes on medical facilities to allow the bashar al-assad's forces to advance on aleppo. a fragile truce are accused of intensifying their attack.

fighting continues in some parts of the country and the u.n. says progress is being made. >> in the first three months of last year zero trucks reached any of the besieged areas in syria. in the last three weeks 236 trucks have served 115,000 people, many of these have received several convoys donald trump has received a further attack from the mainstream republican party. mick romney has condemned donald trump's antics >> i am far from the first to say donald trump lacks the demeanour to aborigine a president, who attributed a reporter's question to her menstrual psych kel, who marked

a brilliant rival who happened to be a woman due to her apartments, who bragged about his marital affairs and laces his public speeches with vulgarity. he says he admires vladimir putin and at the same time called george w bush a liar. that is a twisted example of evil trumping good. [ applause ] going to washington dc. i guess the big question is will donald trump take the bait and respond? >> reporter: the politically smart thing to do would be simply not respond. that's what some of his supporters, for example, sarah pailin is saying he should. the question is does he even have the ability to not yell when he feels he has been targeted. every single time someone has given him - if he perceives the

smallest slight he goes after them, and goes after them hard. he will be proving his point that he doesn't have the temperament. i think he is just about to start speaking. before he does why he would be so mad, he called him a bad businessman, a bully, an are phony, a fraud. listen in to donald trump right now. let's listen in >> i want to thank paul. i love tough people. you need tough people and he is a tough cookie. when we got his endorsement we were thrilled. he is a great guy. i was doing a little bit of a thing called a debate. . [ cheers ]

>> get him out, please. [ cheers ] >> get him out. what are they doing, right? what's the purpose? a little bit of television time, i guess, but i was going to the debate. i was going directly in from florida. i'm down in florida, campaigning there. we're doing very well. we're campaigning against a guy that has the worst voting history in the state of floor day, marco rubio. i call him lightwooit, he is a lightwooit. i don't know. i should do well there. let's hope i do well there. i love florida, but i was going to detroit and i said to my people, i have to stop in maine. i felt i just had to stop in maine.

so i wouldn't say that it is a very direct route, would you say, instead of going this way i went this way and this way and i'm so glad. to put this incredible sold-out crowd and thousands of people outside, to put this crowd together in a period of, what, 24 hours is brilliant. maine is amazing. it is one of the most beautiful places on earth. people don't realise how large your land mass is. i was talking to paul, as large as new england. can i buy some, please? [ cheers ] >> i've been watching with great interest as we get - go down the line. we've had some amazing results. right nearby with new hampshire it was an amading credible thing. by the way-- amazing incredible thing. when i met with people, the

number one problem, heroin. i say how is that possible? you look at these beautiful fields and the beautiful little roads and everything is so beautiful, and it watts the number one problem and it comes from our southern border and we're going to close up that border and we're going to build a wall and stop them from coming in. we're going to stop them. people are going to come into our country but they're going to come in legally. [ cheers ] >> we're going to solve the problem. i watch these p eurekas ndits. -- punnedits. i said we have to do something because we have people that don't know what they're doing in running our country. they don't know what they're doing. we have to do it. it takes guts to run for president. i'm not a politician, i'm not a politician, all talk no action, nothing gets done. anyway, we're coming down and i

said to myself, you know, there's so many things, and then i watched the pundits and they said, "i have some great talent running", and i'm thinking where, what's the talent? you come down and you do it and you start talking about trade and you see what happens with trade. trade has been a disaster. the pundits, i came out at 23%. my wife said you know if you run you're going to win. if they poll it, people will say you're not going to run. she said if you run you're going to win. i said oh. she is my poster. i paid her less money. i started at 3, the first day or something. i was at 3, which i wasn't thrilled about. then it went up to 6, 12 and 18 and kept going up.

they would always say i have plateaued. well, he is going to get six. then i went up to 12. well, you know, a solid group. i went up to 24. that's with 17 people. that's a lot. 24 is good. we entity up to 24 saying that's the max and there won't be any more. so we went up to 32. cnn came out of a poll with 49 you're listening to donald trump at a campaign rally there in oregon. we're going to our correspondent now. a sort of mild mannered speech so far. does it look like he has taken the bait in reacting to mick r, onney? >> reporter: i wish i had an answer for you, but you never can tell. he doesn't have a prepared speech. he basically says whatever comes

to his mind, or it appears so. it would be unusual for him to not attack romney who launched a personal attack. this isn't just about romney v donald trump. this is the entire republican establishment versus donald trump. people haven't tried to attack him, but what you're seeing is a huge fear in washington and the republican establishment across the country. i think i heard another protester. this is becoming a theme at donald trump's rallies, but the crowd actually has been pushing and getting violent with those protesters, just to show you the amount of tension that his campaign brings. not only do you see this speech from mick ronmney but a letter from republicans saying out and saying donald trump would be a dangerous thing for our country. you saw that. now you see the money has followed between the super pack

$. they're getting millions of dollars from big donors saying you need to stop donald trump. they're blanketing the airways with donald trump attacks. the question is, is it too little too late. it probably isn't going to do anything to derail donald trump because now on most of the contest is winner take all. this is the republican party trying to stop him and it's not clear that they can thank you for that. a reminder of our top stories here on al jazeera. frustrated refugees trapped in greece have blocked a railway line into macedonia in protest at the country's refusal to let them in. the u.n. says aid is slowly trickling into syria despite videos which purport to show russian air strikes days after a cessation of hostilities came into effect.

from u.s. republican ronney has attacked donald trump calling him a bully. north korea has been accused of firing what have been described as six short-range projectiles into the sea hours after tough new sanctions were ordered against it. the defense ministry said they were launched from wonsan to the sea of japan. the security national was unanimous in imposing sanctions on the country. >> reporter: in that news conference the ministry of defense in south korea saying a number of projectiles have been fired into the sea off the eastern coast. local media in south korea are reporting more fully. they do sometimes get briefings from unnamed military officials. they're talking of a range of

100 to 150 kilometers. six to nine projectiles. it is unclear whether they were short-range missiles or a multi rocket launching system which was paraded in pyongyang last year. it is understood that analysis is underway on that point. the ministry of defense is saying that the military remains in a heightened state of readiness, watching out for any further actions by its counterparts in north korea. we are coming into a period of annually heightened tensions between north and south because there are military exercises due to get underway in the next few days between u.s. and south korean forces. this year it is expected that it will be bigger and might including rehearsal for a pre-emptive strike. north korea says it reserves the right to attack south korea

seats of government. so we do expect a round of heightened tensions. this is the first north korean reaction to this u.n. security council passage. the resolution passage. it may well be that there is more to follow in the days and weeks to come sunnis in eastern iraq are worried about revenge attacks from shia militias following a bombing on monday. the targets were senior members of the shia militia when were attending a funeral of a colleague. >> reporter: few are venturing to the streets here. the iraqi town is in this province bordering iran. it is strategically important for the she militias. the-- shia militias. it is sunni area. this was the aftermath of a suicide bombing on monday at a funeral attended by commanders

from a shia militia. at least 40 people were killed. >> translation: in a video leaked online the governor is heard blaming the breakdown in security on iraq's prime minister. >> reporter: he said his decision to take responsibility from the police and give it to the military have political and sectarian motives. the mesh is accused of using this attack as an excuse to force sunni civilians from the area. it did the same thing in january when the suicide bombing of a café killed 42 mainly shia people. there were reprisal attacks, including the fire bombing of nine sunni mosques. civilians from all communities are the victims of the violence. much of the man power is dedicated now to areas north of baghdad where it's trying to dislodge i.s.i.l. again here they work together with shia militias.

the aim is to tighten the arm's grip around the i.s.i.l.-held northern city of mosul. in other areas the army works with sunni fighters. here where shia militia are effectively in control, sunni civilians fear they're valuable to intimidation and revenge attacks. bernard smith turkish police have confirmed that two women killed in an armed standoff with police were members of a far left organization. they fired shots and threw a hand grenade at a police bus. they're part of the dhkpc, a group violently opposed to what they see as westernisation of turkey. an outspoken activist for indigenous populations in honor overture as-- honduras has been found shot dead at her home.

she won the prestigious goldman prize last year for her work authorities in the u.s. state of alabama have been criticized for arresting hundreds of pregnant women on suspicion of taking drugs. they're being accused of being over zealous with the law. our correspondent reports from rainbow city in alabama. >> reporter: from an early age this woman always wanted to be a mother and now she has two boys. when she gave boy to one year old james last year things went badly wrong. during her pregnancy she took half a valium and when it turned up in a post-natal blood test, she fell foul of the laws. she gave birth to a perfectly healthy son and her results with passed on to the authorities. the two months later she was arrested at work and taken away in handcuffs.

>> i had a sense of doom and fame ur that there was i was going to recover from this-- failure that i was going to recover from this. i knew in my heart that i had done nothing wrong, but i also know the ways the law works. >> reporter: the law was originally written to tack ema methamphetamine epidemic wherein fants were exposed to dangerous chemicals. since 2006 close to 500 women have been prosecuted under endangerment laws. this doctor says it isn't a right approach. he says dependence on things like pain-killers and a rise in heroin use are a far bigger problem than meth addiction. he is an advocate for support rather than conviction. >> we all know how important a

mother's love is. at the same time criminalising these women making them feel inferior and as bad mother new zealand that sense will leave a mark on them forever. >> reporter: at the public defender's office lawyers are concerned about the rights of women and say blood tests carried out without a mother's consent to have dire consequences. >> we have to foster a situation where people are encouraged to be honest with their caregivers. if we can't do that, then what you will have is people not getting care and you will have people having really bad outcomes because they're afraid of the punishment that would come to them if they were honest. >> reporter: the charges against casey were eventually dropped, but she said she will continue to fight for those would can't speak for themselves scientists from west africa are taking their expertise to south america as they try to stop the spread of zika.

researchers are using their experience with ebola to help with early detection of the virus. >> reporter: this scientist and his team are in high demand. back in december they got a call from scientists in brazil asking for help with tackling the zika outbreak. they travelled to the worst affected region carrying this suitcase. it is a solar power virus detection set. inside the suitcase is a miniature state-of-the-art laboratory with just a tiny blood simple this man and his team can detect whether a person or mosquito is infected with the virus. these machines inside the back allows us to find out the genetic make up of the virus no matter where it is located and whether it is found in the blood, urine or any other bodily fluid >> reporter: currently it takes five days to detect the virus after patient develop symptoms. this can tell whether the virus is present in just 15 minutes.

>> translation: detecting early means we can try to tackle the virus soon and hopefully alleviate suffering for the infected patients. >> reporter: thousands in south america have been infected with the virus and it is spreading. researchers say zika could be link to cases of birth defects such as microcephaly >> translation: we have not found a direct link between zika and microcephaly but there is an association. >> reporter: scientists believe early detention is key in that this relatively simple equipment can make a difference. it was used during the outbreak of ee bowl in west africa. -- ebola. given the zika virus, scientists want to bring out these

suitcases to affected areas as soon as possible. the challenge in tackling the virus is the lack of scientific knowledge, somebodying researchers here have plenty of. zika has been in west africa for more than 40 years. the strain of zika in africa is different, though, and it has not so far been a marriage health hazard here. braz brazilians are using kits modelled on this one. the team is packing its bags one more time to head back to south america to help out it's world wildlife day and this year the focus ask on african and asian elephants. the illegal ivory trade has make tracking of elephants a lucrative business. it is estimated the elegant global population is between 500,000.

asia, especially china, is the main market for ivory. >> reporter: ironically the elephant is regarded as the national animal of thailand yet this country is one of the key transit routes in the illegal trade. a lot of it is trafficked into thailand from africa and then on to countries like laos, vietnam and china. there is a huge domestic demand tore ivo, ry products. the problem is dealing in ivory in wild animals is illegal but from domestic thai el vanities is legal. it makes it difficult for the authorities to determine where the ivory come from. most come from african elephants. last year the government passed a law stating that owners of

domestic animals must register their animals along with any illegally sourced ivory but the demand is still outstripping the legal surprise of ivory you can find out much more on our website. it is aljazeera.com. and intervention come to an end. in the jostling for money and power, competing forces are fighting for the wealth buried deep in the hindu kush mountains. that wealth is precious rubies, which fetch a handsome sum, especially when smuggled across the border. i'm steve chow. on this edition of 101 east, we look at the lives of afghan ruby miners who are risking it all chasing crystal dreams.
