Libya has shut down its air space to all traffic until further notice, Europe's air traffic agency said Friday, hours after the UN approved air strikes against the regime.

Eurocontrol, citing information from Maltese authorities, said in a brief statement on its website that Tripoli "does not accept traffic UFN (until further notice)."

The United States, Britain and France were expected to scramble fighter jets against Gaddafi's forces after they secured the UN Security Council's blessing late Thursday. Paris warned military action was imminent.

The UN Security Council passed a resolution approving "all necessary measures" to impose a no-fly zone in Libya, protect civilian areas and pressure Moamer Kadhafi into accepting a ceasefire.
