Russian President Vladimir Putin told United Nations Secretary General Ban Ki-moon that US strikes against the ISIL in Syria should not be carried out without Damascus permission.

"The Russian side stressed that directing air strikes against the bases of (ISIL) terrorists in Syria should not be carried out without the agreement of the Syrian government," said a Kremlin statement issued shortly after midnight local time (20:00 GMT Monday).

The United States, with backing from five allied Arab states, launched strikes from the air and sea against the Takfiri militants in Syria early on Tuesday.

Russia has earlier this month warned that unilateral US air strikes in Syria would be a violation of international law.

Putin will not attend a UN General Assembly that gathers in New York on Wednesday which is expected to focus much of its attention on ISIL threat in Iraq and Syria.
