Gaddafi tanks shell Libya's third city Misrata
Fears of further bloodshed as regime forces launch heavy artillery attack on rebel stronghold
Tanks shelled the centre of rebel-held Misrata on Sunday, a resident of Libya's third biggest city said, warning of "carnage" if the international community did not intervene.
"Tanks are shelling the centre of the city, near the radio headquarters. We are also hearing heavy automatic weapon fire," the resident said on condition of anonymity. Firing was clearly audible over the telephone.
"The residents are not armed. If the international community doesn't intervene quickly, there will be carnage."
