US forces attempted hostage-rescue in Afghanistan: Pentagon

US forces in Afghanistan last month attempted to rescue two hostages, the Pentagon said today, as US media reported the captives were two American University of Afghanistan professors.
"President Obama authorized US forces to conduct a mission in Afghanistan, aimed at recovering two civilian hostages," Pentagon press secretary Peter Cook said in a statement.
"Unfortunately, the hostages were not at the location we suspected. During the mission, US forces engaged and killed a number of hostile forces. No US personnel or civilians were harmed.
