Al-Qaida said the deadly attack on the U.S. consulate in Benghazi, Libya was in revenge for the killing of the network's number two Sheikh Abu Yahya al-Libi, SITE Intelligence Group reported Saturday.

Prime Minister Najib Miqati denounced on Friday that recent attack on the U.S. Consulate in Benghazi that killed the ambassador and three others, saying that the “friendly” U.S. people shouldn't be held responsible for the work of an “individual” citizen.
