Fighting has intensified in the Libyan port of Misrata as government forces attempted to retake the rebel-held city after a two-month siege. A rebel spokesman said Col Gaddafi is trying to create a humanitarian crisis in the only rebel-held western city. Rebels who have been attempting to end Muammar Gaddafi’s four-decade rule say Nato forces should be doing more to protect its 300,000 residents. In the east, fighting has continued on the coastal road to Benghazi. Reports say, fierce battles on the road between Ajdabiya and the strategic oil town of Brega – which has changed hands half a dozen times since February – killed a number of rebels and wounded many more.
