Yemen's al-Qaeda affiliate has threatened to kill American hostage Luke Somers in three days if its demands are not met, according to a U.S. group that monitors terrorist organizations and jihadist activity.

In the video obtained by the SITE intelligence group, the captive identified himself as 33-year-old Somers, a British-born U.S. photojournalist who disappeared more than a year ago in Yemen's capital, Sana'a.

Somers was among the apparent targets of a rescue attempt last month by a joint Yemeni-U.S. raid that freed eight other captives. But he had been moved before the raid took place, Yemeni officials said afterward.
