The United States, France, Italy and Britain condemned what they described an escalation of violence in and around the Libyan capital Tripoli, warning that armed groups which undermined Libyan stability would be made accountable. The confrontation resulted in closure of Tripoli airport after some rockets were fired in its direction, a spokesman for the state airline Libyan Airlines said.

“These attempts to weaken the legitimate Libyan authorities and hinder the ongoing political process are not acceptable,” Washington, Paris, Rome and London said in a joint statement published by the French foreign ministry.

“We are calling on the armed groups to immediately stop all military action and warn those who seek to undermine stability, in Tripoli or elsewhere in Libya, that they will be made accountable for it,” the statement said.
