Russia is considering how it could cooperate with other nations in the fight against Islamic State militants.
The Kremlin said President Vladimir Putin discussed the issue with senior officials at a meeting of his Security Council on September 22.
Putin's spokesman, Dmitry Peskov, said they "exchanged opinions on possible forms of cooperation with partners on a plan to counter Islamic State in the framework of international law."
The United States is trying to build an international coalition to fight the militant organization, which has seized large swathes of northern Iraq and Syria in recent months.
President Barack Obama said on September 10 that the United States was prepared to attack Islamic State militants in Syria in addition to Iraq.
Russia has said air strikes on Syrian territory without a UN Security Council resolution would violate international law.
