Isis announced Jordanian Air strikes killed American WorkerKayla Mueller. U. S. Facials say theyve seen no evidence of her death. Juliana, good morning. Reporter for more than a year mueller, from prescott arizona, reported as the unidentified american female hostage held by isis. The u. S. Government and her family withheld her name in an effort to secure her safety. With her identity revealed friday the world is learning more about the selfless volunteer. I am in solidarity with the syrian people. Reporter 26yearold Kayla Mueller traveled to some of the worlds most dangerous locations, dedicated to helping the less fortunate. But now after more than a year in captivity, kayla parents are praying for their daughters safe return home. The strain of not knowing where their daughter is at is whether or not shes alive or not is something that is starting to wear on them. Reporter in august 2013 mueller was kidnapped in syria leaving a hospital run by an aid group. Nine moss later, muellers captives provided proof she was alive. July 2014 u. S. Special Operations Forces found strands of hair believed to be from mueller after an unsuccessful rescue attempt to save hostages in the syrian city of raqqa. On friday isis said mueller was killed in one of the Jordanian Air strikes seeking to destroy the terrorist group strondholds claims she was killed in raqqa, when the building collapsed on top of her. On sunday dismissed the claim as propaganda. What we know about them theyre liars and have no respect for human life. Thats why its very difficult to actually make any ak krut accurate assessment or conclusion regarding the fate of the american lady. Reporter if muellers death is confirmed, she would be the fourth american hostage killed while in isis captivity, but close Family Friends remain hopeful. This thing, its time to van ending. Time to bring kayla home to hur parents and family. Reporter the u. S. Government has not corroborated the report of muellers death. Muellers parents released a statement asking her captors to contact them privately. In iraq the staunchest allies in the battle guess isis are known as the peshmerga, growing frustrated with what they say is lack of u. S. Support. Holly williams is in irbil. Good morning. Reporter good morning. We traveled to mount sinja, a land recently recaptured in isis militants. The peshmerga are the foot soldiers in the fight against isis facing off with the extremists on a 600milelong front line. Theyre kurdish soldiers and in iraq they have the best track record of defeating the militants, but theyre massively outgunned. The Kurdish Forces say theyve clawed back 1,500 square miles of territory from isis since december. And theyve done nearly all of their fighting relying on small caliber weapons like these. We have lost more than 1,000 peshmergas, and somewhere around 5,000 wounded. Reporter this man, the Kurdish National security adviser, told us 70 of those deaths could have been prevented, if the u. S. Would give the peshmerga the hundreds of Armored Vehicles they want. So far, theyve received just 25. Thank the peshmerga. That is not enough. We need the equipment. This is a war. The enemy doesnt wait wait for us or allies to provide the right equipment. Reporter the amered car would offer some protection against the biggest killer of the kurdish fighters car and roadside bombs. In a battle last month, isis attacked them with 14 car bombs in just one day. What do you say to the families of those men who have died . Whose deaths were preventible . These are our heroes. We need to protect these heroes and i think they are the heroes of the free world, and its the responsibility of the International Community to protect them. Reporter the reason the u. S. Is reluctant to directly equip the peshmerga is that the Kurdish People want independence, and helping them angers both the Iraqi Government as well as the authorities in turkey where theres a large kurdish population. But that leaves the peshmerga desperately underequipped. Charlie . Holly, thanks. North carolina flags are flying at halfstaff this morning for hall of fame basketball coach dean smith.
