TRIPOLI (Reuters) Western forces hit targets along the Libyan coast on Saturday, using strikes from air and sea to force Muammar Gaddafi's troops to cease fire and end attacks on civilians.

French planes fired the first shots in what is the biggest international military intervention in the Arab world since the 2003 invasion of Iraq, destroying tanks and armored vehicles in the region of the rebels' eastern stronghold, Benghazi.

Hours later, U.S. and British warships and submarines launched 110 Tomahawk missiles against air defenses around the capital Tripoli and the western city of Misrata, which has been besieged by Gaddafi's forces, U.S. military officials said.

They said U.S. forces and planes were working with Britain, France, Canada and Italy in operation "Odyssey Dawn".

Gaddafi called it "colonial, crusader" aggression.

"It is now necessary to open the stores and arm all the masses with all types of weapons to defend the independence, unity and honor of Libya," he said in an audio message broadcast on state television hours after the strikes began. http://news.yahoo.com/s/nm/ts_nm/us_libya
