In Libya, troops loyal to Col.Gaddafi today pounded the western town of Misurata, which has been under its siege for weeks, as rebel forces in the east were involved in a seesaw desert battle for control of the strategic oil town of Brega. Western media reports said, massive shelling by government forces killed at least one person and wounded several others today in Misurata, the main rebel stronghold in the west. Reports said, it is unclear who controls Brega, which has been the scene of fierce fighting over the past few days when pro-Gaddafi forces returned after being driven out by rebel forces. Amid conflicting reports, the rebels claimed that they had regained control over Brega, 800 km east of Tripoli. Al Jazeera channel said, however, the opposition's advance appeared to be slow and uncertain despite two weeks of air strikes targeting the Col. Gaddafi's forces by the western military coalition. The Arab channel said, the opposition forces have advanced to a walled university campus near the town's western edge.
