only on al jazeera america. >> the coalition agrees to a humanitarian pause in yemen. hello and welcome to al jazeera live from our doha headquarters. coming up, turkey continues its bombardment of the pkk in iraq and isil targets in syria. >> so you feel like my given african name to be truly blessed. >> a return from barack obama after a day of tough talks with

kenya. >> reporter: i'm in the rice patties of hong kong being farmers for a day. >> first the coalition announced a humanitarian pause to the fighting in yemen. but aid workers don't know how this will help to get aid to people. and the fighting on the ground hasn't stopped either. a warning some viewers may find the images and report disturbing. >> reporter: the coalition military planes are arriving. after four months of fighting, the airport is under the control of pro government fighters. it's after taking this area, that they announced a five day pause. it says the truce comes at the president to allow in

humanitarian aid. saudi arabia will respond to any houthi attacks. >> the goal is to help lift the siege on the cities and reach those areas with much needed humanitarian aid. it is another opportunity for the houthis. >> the houthis say the so you did i backed government is out of touch with the reality on the ground and that saudi strikes are killing civilians. the rebels say a residential area was also hit including a shelter for internally displaced people, dozens were killed. houthi activists uploaded have uploaded this video of women and children. it means little aid has made it through and the humanitarian situation has become worse. roads have been damaged or being held by fighters.

the military say they have held off houthi advances and fortifying positionings. >> translator: our goal is to liberate them and help those displaced to go back to their homes. we want to build a modern civil state for us and our children. >> reporter: the destruction is everywhere. journalists are trying to document the damage. aid agencies welcomed the brief cause, but calling for a lasting cease fire to reach those who need aid. >> the situation is dire. we are talking about 20 million people in need of humanitarian assistance, healthcare water food shelter and all the rest. so we desperately need a resolution to this conflict. >> reporter: which ever side prevails it will be left with a yemen that's tattered and exhausted. the united nations declared

yemen a level 3 humanitarian emergency, the highest on its scale. according to the u.n., nearly 1700 civilians have been killed since saudi led air strikes began in march. the fighting has left 1 million people displaced. estimated 21 million people, that's roughly 80% of the population, are in dire need of food and aid. 20 million have no access to clean water. unicef is warning that half a million children under the age of 5 are at risk of developing severe malnutrition. it is believed the humanitarian pause will last the full five years. >> at the end of the fifth day they witnessed a lot of air strikes. the second was supposed to take

place after the geneva talks. it seems that cease fire was announced to catch the houthis off guard and capture the city of aden. the saudi led coalition made a lot of advancements in yemen. they freed aden through operation golden arrow. yesterday there was an attack that took place in a city. they bombed electricity station. they hit the residential city right next to it that had technicians living there with their families. so there are reports of 35 to 100 people being dead there with numerous other injuries ranging from the hundreds. so it seems that the cease fire is a way to kind of calm the media down and distract away from this attack that was directly aimed at civilians women and children. strategically speaking, i cannot

see the coalition taking the step. now to some news that's just coming out to us from turkey. it's been reported that two policemen have been killed in a car bombing. we understand that four others have been wounded. they have traveling in their convoy in the mainly kurdish southeast of the country. it's late on saturday night. that's all we have at the moment. two turkish soldiers killed, four wounded in a car bomb attack in the southeast of the country. meanwhile turkey has carried out more air strikes aimed at the pkk in northern iraq. fighter jets have also targeted the isil in syria. the syrian observatory says villages north have so far been targeted. it says the border town was also struck.

many believe the decision to actively engage in the fight against the armed group has a lot to do with the battlefield in northern syria. the government here is concerned about isil threatening syrian opposition groups in their strong hold in alepo province. it is worried about what it sees is the growing strength of syria's kurds. syria's kurds now controls more than half of the 800-kilometer border with turkey. turkey says it would be a red line if kurds create a state in northern syria. officials blamed u.s. air strikes for helping the kurds gain ground from isil. now there are those who believe a deal with united states addresses turkey's concerns. >> translator: turkey doesn't want the ypg to take more territory. the u.s. supported the kurds. now it withdrew its support. but it will not last forever. now the u.s. and turkey are

working together. >> reporter: turkey's fear is that syrian kurds or isil could drive out opposition groups and control the important border crossing. it is no coincidence that turkish jets targeted isil close to the front lines with turkey backed syrian rebels. the demand for a humanitarian safe zone will emerge. >> translator: our aim is to get rid of the isil threat in syria and iraq. after that, the zones will be formed naturally. >> reporter: the peace process to stop a decades long conflict with the separatist movement seems to have officially ended. turkish police have conducted raids against hundreds of suspected pkk and isil sympathizers. there could be attempts to destabilize turkey from within. iraqi kurds have been

and that they are deserving of equal protection under the law and that the state should not discrimination against people based on sexual orientation. and i say that recognizing that there may be people who have different religious or cultural beliefs. but the issue is how does the state operate relative to people. >> but there are some things we must admit we don't sure, our culture, our societies don't accept. it's very difficult for us to be able to impose on people that which they themselves do not accept. this is why i repeatedly say for kenyans today the issue of guy rights is really a nonissue. we want to focus on other areas that are day-to-day living for

our people, the health issues with discussed with president obama is critical. republican presidential contender donald trump has gone on the attack with his democratic rival, hillary clinton, for the use of her personal e-mail. >> with hillary, she's supposed to be running not against me, she's not favored. but she's favored to win. look, if the prosecutors are honorable, and they may be, if they are fair, if they are just, sadly, bad stuff has to happen because what she did is very criminal and very serious. and it's too bad. it's too bad. [applause] and i don't know how a person with that cloud over their head can be running for the office of president. you wouldn't think so. so we'll see what happens. it will be very interesting.

while speaking to reporters hillary clinton denies doing anything wrong. >> there is so much confusion around this. i understand why reporters and the public are asking questions. the facts are clear. i did not send or receive anything that was classified at the time. more to come, including the struggle to weed out a controversial chemical from france's farming and gardening industry. and how turning to new technology is saving the lives of mothers and their babies in the developing world.

and they may dampen down the number of jobs there because they become more expensive to employers. >> reporter: critics have been looking at numbers out of seattle that might suggest that employers have opted to hire fewer workers. but opponents say it's too early to tell. meanwhile, it looks as though the momentum is building for that $15 minimum wage across the country. the bolivian government failed to reach an agreement with the striking miners. they are demanding that the president fulfill his promise to create more job opportunities. 20% of the libyan mining companies are working at a loss. that's prompted anger for failing to invest in infrastructure. brazilian prosecutors charged 22 business executives
