Heavy explosions heard in Libyan capital

Signals of the country's state TV were cut off after at least four explosions jolted several districts of Tripoli at about 2210 GMT.

The targeted sites could not be immediately identified.

On March 17, the UN Security Council adopted a resolution imposing a no-fly zone over Libya, paving the way for a military operation against embattled Libyan leader Muammar Gaddafi which began two days later.

The command of the operation was shifted from a US-led international coalition to NATO in late March.

Despite dozens of sorties carried out by NATO aircraft against Gaddafi's forces, the government troops maintain their combat capability and continue to pound poorly-equipped rebels with heavy artillery and rocket fire.
