Tripoli, March 20 (IANS) At least 48 people were killed and 150 others wounded in air strikes carried out by coalition forces to enforce a UN resolution imposing a no-fly zone over Libya, Xinhua reported Sunday.

Anti-aircraft gunfire was heard in Tripoli early Sunday as warplanes flew over the Libyan capital. Pro-Gaddafi supporters gathered in downtown Tripoli to protest against the air strikes.

French warplanes attacked an air defence site in Tajura, about 10 km east of Tripoli, and destroyed several armoured vehicles of the Libyan government troops near Benghazi, the last stronghold of Libyan rebels, Saturday night.

The US military said 112 Tomahawk cruise missiles were fired from US and British warships and submarines at more than 20 targets in Libya.

Libyan Parliament Speaker Mohammed Abul-Qassim al-Zwai said at a press conference that foreign fighter jets hit Tripoli and Misurata, which caused many casualties.

Libyan state-run television said Sunday at least 48 people were killed and 150 wounded in the air strikes.
