The April 14 gathering will focus on political solutions to the crisis and "reinforce coordination between the Arab League, UN, African Union and Organisation of the Islamic Conference (OIC)," league number two Ahmed Ben Helli said.

Amr Mussa, who heads the 22-member pan-Arab body based in the Egyptian capital, OIC chief Ekmeleddin Ihsanoglu and Jean Ping, head of the African Union Commission, will also attend the conference.

The gathering will take place a day after a meeting of the Libya contact group, set for April 13 in the Qatari capital Doha.
