The European Union's foreign policy chief has called on all sides in the escalating Libyan military conflict to stop fighting and start talking.

Federica Mogherini said Monday that European Union foreign ministers meeting in Luxembourg were united in their call for a truce.

Mogherini says all sides in the recent surge in fighting should "go back to the negotiating table under the auspices of the U.N. and make sure that the Libyan people get what they really want, which is peace and stability for their country."

The U.N. says that fighting over Libya's capital that erupted last week has already displaced 2,800 people. The death toll has risen to 49, including civilians.

Libya is a departure point for many refugees trying to cross the Mediterranean to Europe.

The only functional airport in the Libyan capital has announced it was hit by an airstrike amid clashes between rival armed groups for control of Tripoli. No casualties were reported.

The official Facebook page of the Mitiga airport said a fighter jet attacked the facility on Monday. There were no other details.

A video circulated online shows a fighter jet firing and allegedly targeting the airport. The facility, located 8 kilometers (5 miles) east of the city center, originally functioned as a military base.

The fighting for Tripoli erupted last week when the self-styled Libyan National Army, led by Khalifa Hifter, began an offensive against the capital, clashing with rival militias that support the U.N.-backed government.

The U.N. humanitarian coordinator in Libya says 2,800 people have been displaced by fighting between rival militias over the capital, Tripoli.

Maria do Valle Ribeiro said Monday that clashes have prevented emergency services from reaching casualties and civilians, and have damaged electricity lines.

She warned that the increased violence is worsening the situation for migrants held in Tripoli's detention centers.

Fighting was underway Monday at the international airport, some 24 kilometers (15 miles) from central Tripoli.

The self-styled Libyan National Army, led by Khalifa Hifter, began an offensive against the capital last week.

Rival militias that support the U.N.-backed government in Tripoli have vowed to recapture all the areas recently seized by Hifter's forces.

The two sides reported that at least 41 people, including civilians, had been killed since Thursday.
