The Israeli military said Monday it is poised to lift a closure on its northern airspace imposed a day earlier as part of an alert that followed air strikes on Syria.

"Civilian aviation in northern Israel will resume regular operation following security assessments," it said in a statement.

An army spokeswoman told the AFP news agency that the closure, originally scheduled to last until May 9, was expected to end later on Monday.

A senior Israeli source confirmed to AFP that the Jewish state had carried out a pre-dawn attack on a site outside Damascus on Sunday, in the second such attack in 48 hours, both of which had targeted weapons destined for Lebanon's Hizbullah.

Syrian officials warned in response that "missiles are ready" to retaliate.

Following Sunday's strike, the Israeli air force went on high alert, although the Jewish state appeared not to be anticipating a significant response from Damascus.

Two batteries of the Iron Dome missile defense system were moved to the north of the country and Israeli media reported security in embassies around the world had been heightened due to the tensions.
