Libya: UN quits Tripoli amid mob attacks

The UN says it is pulling out all its international staff from the Libyan capital Tripoli, following damage to its offices there.

UN buildings and some foreign missions were targeted by angry crowds following a Nato air strike that reportedly killed a son of Col Gaddafi.
The UK says it is investigating reports that its residence had been destroyed.
Protests were also reported outside the US and Italian missions in the city but it is not clear if they were damaged.
A witness told Reuters news agency that smoke could be seen coming from the roof of the Italian embassy. Italy recently joined the Nato mission in Libya.
Late on Saturday, the Libyan government said Saif al-Arab 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".
Early on Sunday, angry crowds gathered outside Western missions in the city.
"We are aware of reports that the British Residence in Tripoli has been destroyed, and are currently investigating them. We believe that other foreign residences have been attacked as well," a spokeswoman for the UK's Foreign Office said.
"Such actions, if confirmed, would be deplorable as the Gaddafi regime has a duty to protect diplomatic missions. This would be yet another breach of Gaddafi's international obligations."
The UK has withdrawn diplomats from Tripoli.

Pro-Gaddafi supporters have made public displays of loyalty for the embattled Libyan leader

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.
"How is this helping in the protection of civilians? Mr Saif al-Arab was a civilian, a student," Mr Ibrahim said.
"He was playing and talking to his father and mother and his nieces and nephews and other visitors when he was attacked and killed."
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 from the scene unscathed.
Russia expressed "serious doubts" that the West was not targeting Col Gaddafi and his family.
"The claims of the coalition members that strikes over Libya do not have the physical destruction of Muammar Gaddafi and members of his family as their goal cause serious doubts," a statement from the foreign ministry said.
"Reports of casualties among civilians are being received in Moscow with increasing concern," it added.
In the eastern rebel stronghold of Benghazi, shots were fired in celebration following the reports that Saif al-Arab Gaddafi had been killed.
On Saturday, Nato officials said the alliance would not consider talks until government forces stopped attacks on civilians.
The vice-chairman of the rebel Transitional National Council also rejected the offer of negotiations.
