The political turmoil in Libya is exposing a growing gulf between rival Arab states. It is also defining a proxy war over the threat to the region's old order since the start of the Arab Spring.
The United Arab Emirates is accused of carrying out air strikes on militias in Libya with support from Egypt. Two bombings in eight days are said to have caught the US completely by surprise.
The UAE has dismissed the claims as a "diversion", while Egyp's President Abdel Fattah El-Sisi has denied any involvement.
The Arab uprisings and the events that followed have upset the established state system in the Arab world and seen the emergence of new alliances.
Saudi Arabia, the UAE and Egypt are viewed as having a common goal in trying to contain or eradicate political Islam, while Qatar and Turkey are seen as more sympathetic to these causes.
So is a simmering proxy war in the region spilling over to direct involvement? Who is backing whom? And what is the role of the US?
