Heavy shelling resumed in the Libyan capital Tripoli on Sunday after three days of relative calm following more than a month of street fighting between rival armed factions battling for control of the city's airport, Reuters reported.
Southern Tripoli was covered by black plumes of smoke, with artillery and rockets hitting areas around the international airport, where two rival brigades of ex-rebels have established front lines.
There were no immediate reports of casualties from the new exchanges. But the health ministry said it cannot reach hospitals because of power failures and gasoline shortages in Tripoli.
