Arab League Secretary General Nabil El-Arabi left here on Tuesday for Paris to take part in a two-day International Support Group for Lebanon (ISG). The conference comes in the context of the major effort to support Lebanon, an effort that the ISG launched on Sept. 25, 2013, on the sidelines of the UN General Assembly. Arabi is scheduled to head later for Rome to attend a conference on Libya friends, slated for Thursday, to discuss the main challenges facing Libya in the current phase, especially the security uncertainty and terrorism.
