Libyan officials have accused NATO of killing at least eight people in an air raid on a food warehouse and medical clinic in Zlitan, east of Tripoli.

Foreign journalists taken to the town of Zlitan on Monday were unable to verify if it was a NATO operation.

NATO has denied targeting civilians and say it only hit military facilities in the area.

Muammar Gaddafi, the longtime leader, remains in power despite a four-month NATO air campaign and five months of fighting with opposition fighters who have seized large parts of the oil-rich North African country.
