Militia infighting continues in Libya's Tripoli
Heavy shelling has continued in the Libyan capital Tripoli following three days of relative calm.
Clashes resumed on Sunday between rival militias over the control of the main international airport in the country.
The militias from the town of Zintan, who have controlled the airport since the overthrow of former dictator Muammar Gaddafi in 2011, have been engaged in fighting with their rivals from the city of Misrata since July 13.
There has been no report on casualties but health officials say a lack of fuel has made it practically impossible to reach the affected areas.
United Nations representatives have been in Tripoli since Friday to broker a ceasefire between the two sides of the conflict.
“The mission has already met several key actors and is still fairly optimistic that a ceasefire can be obtained,” an official from the UN delegation said.
“The delegation is very concerned about the humanitarian consequences of the ongoing crisis if a ceasefire is not achieved very quickly.”
Nearly three years after the fall of Gaddafi, Libya is still grappling with rising insecurity as the country has been witnessing numerous clashes between government forces and rival militia groups.
The former rebels refuse to lay down arms despite efforts by the central government to impose law and order.
Thousands of angry Libyan demonstrators frequently take to the streets in a number of cities to protest against lack of security across the North African country.
