10 al-Qaida militants killed during the course of US-led raid attempting to rescue hostages

Yemeni security officials say a high-risk, U.S.-led raid attempting to rescue hostages a day earlier killed ten al-Qaida militants.

The captives — American photojournalist Luke Somers and South African teacher Pierre Korkie — died of wounds sustained during the raid.

The officials spoke Sunday on condition of anonymity because they were not authorized to brief reporters.

About 40 American special operations forces were involved in the rescue attempt, which followed U.S. drone strikes in the area, U.S. officials said.

Following a firefight with militants, the rescuers eventually reached the men and found them alive but gravely wounded. They both died shortly after.

On Thursday, al-Qaida released a video showing Somers and threatening to kill him in three days if the U.S. did not meet the group's unspecified demands.
