World powers said Monday they supported the lifting of an arms embargo on Libya and were ready to supply weapons to the country's new unity government to help it fight the growing threat posed by the Islamic State group.

"The Government of National Accord has voiced its intention to submit appropriate arms embargo exemption requests to the UN Libya Sanctions Committee to procure necessary lethal arms and materiel to counter UN-designated terrorist groups and to combat (IS) throughout the country. We will fully support these efforts," read a statement by US Secretary of State John Kerry and 24 other top diplomats after talks in Vienna.
