Pakistan's army chief has condemned a U.S. drone attack that killed more than three dozen people, saying the missiles struck a peaceful meeting of tribal elders.
Gen. Ashfaq Parvez Kayani called Thursday's strike "unjustified and intolerable" and said it was a violation of human rights.
Pakistani intelligence officials initially said the 38 people killed in a compound in the North Waziristan tribal area were militants meeting to discuss the war in Afghanistan.
They spoke on condition of anonymity because they were not authorized to talk to reporters.
Civilian casualties from drone strikes are a main source of friction between the Pakistani and U.S. governments.
