Amman, Jordan (CNN)Was an American hostage held in Syria killed by a Jordanian airstrike? That's what ISIS said in an online posting Friday, claiming that she died in the group's de facto capital, Raqqa. The posting Friday included a picture of a collapsed building and a claim that the woman -- confirmed by her family to be Kayla Mueller -- was being held there. But it did not show a body or provide any proof of death. Jordanian government spokesman Mohammed al-Momani said his country is looking into the claim. But, he said, "we are highly skeptical" because of ISIS's proven lack of credibility, and he questioned whether they could identify Jordanian warplanes so high in the sky or would hold a hostage in a "weapon warehouse."
