U.S., British, and French coalition forces began Operation Odyssey Dawn Saturday, firing missiles into Libya to enforce a U.N. mandated no-fly zone. Tanks and air defenses were targeted to curb Col. Moammar Gadhafi's deadly assault on rebel forces. A building in Gadhafi's compound reportedly was hit by a missile, though the Pentagon insists this is not an attempt to overthrow Gadhafi. The New York Times' Elisabeth Bumiller looks at the weekend's events and talks about the Pentagon's plan.
