Groups loyal to Muammar Gaddafi, the Libyan leader, have attacked the United Nations and foreign missions <br /><br />in Tripoli.<br /><br />The attacks have forced the UN to evacuate its international staff from the country, out of fear for their <br /><br />safety. Twelve staff members have now been sent to Tunisia from the Libyan capital.<br /><br />On Sunday, Gaddafi's supporters ransacked offices and torched the British and Italian embassies.<br /><br />The violence came after the Libyan government said a NATO air strike killed Gaddafi's son - Saif al-Arab - <br /><br />and three of the leader's grandchildren.<br /><br />The UN has complained to the Libyan government, which has apologised, blaming an angry mob for the damage <br /><br />and promising to repair it.<br /><br />Meanwhile, in the western battleground of Misurata, government forces have stepped up attacks on the <br /><br />rebel-held city.<br /><br />An opposition spokesman says shells started landing as an aid ship was trying to unload.<br /><br />Al Jazeera's Stefanie Dekker reports.
