The United States, Italy and Libya's allies and neighbours agreed in Vienna on Monday to exempt the Government of National Accord (GNA) from a UN arms embargo to help it confront the threat from the Islamic State (IS) group.
The GNA urged the international community "to take responsibility and to accelerate the implementation of its promises" including the exemption to the embargo on weapons sales, in a statement published on its Facebook page.
The jihadist group claimed responsibility for yesterday's bombing which according to the military killed at least seven people in Buairat el-Hassun, 60 kilometres west of Sirte.
IS said the attack was carried out by two suicide bombers -- a Sudanese fighter and another foreigner whose nationality was not given.

Twenty-five other members of forces loyal to the GNA were killed in fighting with IS in Abu Grein, a key crossroads further west, the military said.
Libya was left with two rival administrations after a militia alliance took over Tripoli in mid-2014, setting up its own authority and forcing the elected parliament to flee to Tobruk in the country's far east.
But armed forces loyal to the other government based in the far east are also preparing to battle IS.
