Libya’s war zone has claimed a top commander: The head of Libya's rebel army, Abdel Fattah Younes, was killed along with two of his aides on Thursday. Younes was Gaddafi's interior minister before joining the opposition back in February, and had been arrested, along with his aides, by rebels earlier Thursday under suspicions that his family might still be linked to Gaddafi's regime. Summoned to discuss "a military matter," Younes and his aides were reportedly shot dead before they arrived for questioning. The head of the National Transitional Council did not directly blame Gaddafi for Younes' death, but cautioned rebels to be aware of "armed groups" in the towns that they currently occupy. Meanwhile, four rebels were killed and 10 more injured in clashes with loyalists near the Tunisian border.
