WASHINGTON (AP) - Libyan air defense facilities are under attack by U.N.-backed coalition forces. The Pentagon says 112 Tomahawk cruise missiles have hit some 20 sites so far. Navy Vice Adm. William E. Gortney says the attacks are aimed at clearing the way for imposition of a European-led no-fly zone over the North African country. He says the missiles were fired by U.S. and British ships and submarines.
