ISIS Frees 49 Hostages

The Turkish prisoners were held for three months

ANKARA, Turkey—Turkish authorities say they have freed 49 hostages from one of the world's most ruthless militant groups without firing a shot, paying a ransom or offering a quid pro quo.

But as the well-dressed men and women captured by the Islamic State group more than three months ago clasped their families Saturday on the tarmac of the Turkish capital's airport, experts had serious doubts about the government's story.

The official explanation "sounds a bit too good to be true," said Sinan Ulgen, a former Turkish diplomat who chairs the Istanbul-based Centre for Economics and Foreign Policy Studies. "There are some very legitimate and unanswered questions about how this happened."
