CAIRO (AP) — A strange silence has met the U.S. capture of a Libyan militant accused in the 2012 attack that killed the American ambassador and three others. In his hometown of Benghazi in eastern Libya, there have been few threats of revenge, only speculation among supporters and opponents that Ahmed Abu Khattala was betrayed by an insider.

Abu Khattala had said for months he had no fear of the Americans snatching him, living at his home and saying he worked as a construction contractor. Before U.S. commandos snatched him from Benghazi a week ago, he had been battling alongside the militant group Ansar al-Shariah against the troops of Khalifa Hifter, a renegade Libyan general who has waged an offensive aimed at crushing Islamic militants around Libya, Abu Khattala’s brother Abu Bakr told The Associated Press.
