WASHINGTON (Sputnik) — Cotton stated:
"We should renew our request that they [Iraq] exclude Russian aircraft from their airspace, and our militaries to be prepared to assist them in excluding Russian aircraft from their airspace."
Russia, Syria, Iran and Iraq have established the Baghdad Information Center in the Iraqi capital to coordinate intelligence and security cooperation against the Islamic State.
A US-led coalition of some 60 nations has also been bombing Islamic State positions in Syria since September 2014, but without the approval of the UN Security Council or the Syrian government.
The United States, which has been supporting the so-called moderate Syrian opposition and calling for Assad to step down, has accused Russia of targeting Assad’s opponents rather than Islamic State positions.
Russia has dismissed such allegations, noting that they lack factual evidence.
