In Libya, heavy fighting has erupted south of Tripoli after Libya's UN-backed government announced a counter-offensive against insurgent forces.

It comes after days of limited advances by either side, in clashes which have killed 220 people.

Soldiers loyal to Gen Khalifa Haftar launched an attack earlier this month to seize Tripoli.

Meanwhile, Libyan Prime Minister Fayez al-Serra has condemned the "silence" of his international allies amid the fighting.
