A coalition of the United States and four other nations launched military action against Libya on Saturday, officials said, as the West tries to force Muammar Gaddafi from power. A U.S. official told reporters on condition of anonymity that a coalition including the United States, France, Britain, Canada and Italy had begun launching strikes on Libya designed to cripple Muammar Gaddafi's air defenses. At least some Arab nations are expected to join the coalition later, the official said.
