The upper house of the Russian parliament, the Federation Council, unanimously approved Wednesday's request of President Vladimir Putin to deploy military force in Syria, President of Sergey Ivanov's head of state said.

The Kremlin leader states that the decision to use the Russian Army abroad only applies to the Air Force, not to the land forces, is transmitted by the RIA.

Although the Kremlin did not specify in its request the country to which the decision was made, Ivanov said after the vote: "It's Syria."

Ivanov also said that Syria had requested military assistance from Russia.

Russia is currently strengthening its military presence in Syria and Moscow stands firmly behind the regime of Syrian President Bashar al-Assad.

The last time the parliament approved Putin to send troops abroad was last year on the annexation of the Ukrainian Crimea.

The Kremlin sent a request to the senators in the Federation Council for the "deployment of a military contingent of the Russian Federation" outside the country on the basis of "generally recognized principles and norms of international law," the AFP reported.
