Libya conflict: Gaddafi family 'flee to Algeria'
The wife and three children of fugitive Libyan leader Muammar Gaddafi are in Algeria, Algerian officials say.
A foreign ministry statement said Col Gaddafi's wife Safia, daughter Ayesha and sons Muhammad and Hannibal left Libya early on Monday.
Algeria's UN ambassador said they were received on humanitarian grounds.
Meanwhile rebels said they had uncovered four mass graves in recent days.
