UN is withdrawing all international staff from the Libyan capital Tripoli following a mob attack on its offices. UN buildings and some foreign missions were targeted by angry crowds following a NATO air strike that reportedly killed a son of Col Gaddafi.
After its Tripoli embassy was sacked, the UK expelled the Libyan ambassador. A BBC team in Tripoli said the British embassy was completely burnt out with fires still smouldering and paperwork and other debris scattered outside.
In other developments, witnesses reported heavy shelling by pro-Gaddafi forces on the port of Misrata on Sunday. The city has been besieged for two months. Libyan state TV said the port was shelled to stop NATO delivering weapons to insurgents but rebels said an aid ship had been trying to unload.
UK Foreign Secretary William Hague said Libyan ambassador Omar Jelban had been given 24 hours to leave the country. By not protecting diplomatic missions, the Gaddafi regime had once again breached its international responsibilities and obligations, said Mr Hague.
He added: The attacks against diplomatic missions will not weaken our resolve to protect the civilian population in Libya.
The Italian foreign ministry condemned the acts of vandalism on its embassy, describing them as grave and vile. Italy - which closed its embassy in March and is represented by Turkey - recently joined the NATO mission in Libya.
There were also protests outside the US mission in Tripoli.
A UN official said the Libyan government had apologised for the attack on its offices, blaming an angry mob for the damage.
Most Western governments evacuated staff from Tripoli when an international coalition began air strikes on Libya several weeks ago.
Late on Saturday, the Libyan government said Saif al-Arab Gaddafi and three of Col Gaddafi's grandchildren had died in a NATO attack on a villa in Tripoli.
Foreign reporters were shown widespread damage to the building in Col Gaddafi's Bab al-Aziziya compound. NATO has insisted its raid targeted a command-and-control building, and that all Nato targets were military in nature.
Libyan government spokesman Moussa Ibrahim said Col Gaddafi and his wife had been in the building at the time of the attack but they were both unharmed. He said the air strike was against international law and a direct operation to assassinate the leader of this country.
NATO is operating in Libya under a strict UN mandate to protect civilians.
Later on Sunday, Libyan state TV said funerals for Saif al-Arab Gaddafi and the other victims would be held on Monday after noon prayers. The BBC's Christian Fraser witnessed the damage and said that if Col Gaddafi had been there, it is hard to imagine he could have walked away unscathed. (BBC).-
