Rival forces clashed in the Libyan capital Thursday, witnesses and pro-Government of National Accord (GNA) forces said, a day after a UN Security Council resolution called for a "lasting ceasefire". Flights were again suspended at Mitiga, Tripoli's sole functioning airport, following rocket fire, as fighting broke out between forces loyal to the UN-recognised GNA and fighters of strongman Khalifa Haftar in the capital's south. ila/sw/fz
