Britain and other world powers say they are ready to arm the Libyan government to help tackle Islamic State militants, following a summit in Vienna.

The Foreign Secretary Phillip Hammond, who attended the talks, said there was "strong support" from the international community for the new Libyan government and prime minister Fayez Serraj.

Libya is under a UN embargo imposed to keep lethal arms away from terrorists and rival militias vying for power, but the Libyan government of national accord (GNA) is set to apply for an exemption to allow it to equip its forces to take on IS - also known as Daesh - which has made inroads in the troubled North African state.

The country is also set to receive help in tackling the human traffickers behind the migrant crisis in the Mediterranean.

Mr Hammond said Britain stands "full square" behind the new government.
