Arab leaders gathered at a summit in Egypt will announce the formation of a unified regional force to counter growing security threats, according to a draft of the final communique, as conflicts rage in countries such as Yemen and Libya.

The summit will also call on Iranian-allied Houthi armed groups who have made rapid advances in Yemen to leave that country's capital and hand over their arms to "legitimate" authorities, said the draft, obtained by Reuters.
