Soldiers, sniffer dogs and rescue workers were searching the ruins of the Plasco building after it crashed down in a giant cloud of dust. The collapse was shown live on state television and one witness described it as "like a horror movie".
By Idrees Ali and Phil Stewart WASHINGTON (Reuters) - More than 80 Islamic State militants, some of whom were believed to be plotting attacks in Europe, died in U.S. air strikes on camps outside the group's former North African stronghold of Sirte in Libya, the United States said on Thursday. "These strikes were directed against some of ISIL's external plotters," U.S Defense Secretary Ash Carter told a Pentagon briefing, using an acronym for Islamic State, the Syria- and Iraq-based militant group.
