NATO warplanes bombed several military and civilian targets in Tripoli, resulting in casualties Saturday night.

Three loud explosions were heard near the Women's Military Academy in downtown Tripoli after NATO fighter jets flew over the capital, a Xinhua correspondent said.

The NATO airstrike also targeted cities of al-Khums and Sirte, destroying water-supply and sewage systems as well as private cars, the state-run JANA news agency quoted the Libyan military as saying.

Earlier on Saturday, NATO said a U.S. unmanned Predator drone hit a rocket launcher of Libyan leader Muammar Gaddafi's forces in the western city of Misrata.
