Several shells have hit the terminal of Libya's main airport as rival armed groups fought in Tripoli for a fifth straight day, and gunmen assassinated a female politician in the country’s east.
In another sign of growing turmoil, air controllers on Thursday halted work in Tripoli, shutting off much of the oil-producing country from international traffic.
Tripoli International Airport has been a battlefield since fighters attacked it with heavy guns on Sunday to wrest control from a rival militia which has been based there since the fall of Libya's late ruler Muammar Gaddafi in 2011.
The conflict is fuelling worries that Libya is on the point of turning into a failed state where a weak central government is powerless to control the militias which helped oust Gaddafi in 2011.
The airport fighting pits brigades from Misrata, a western coastal town, against rival fighters from Zintan in the northwest.
On Thursday, several shells hit the airport terminal where the Zintanis are holding out, striking the main building for the first time, witnesses said.
