There was "significant damage" to a Syrian airfield caused by US airstrikes overnight, according to reports - including the destruction of nine planes.
Russia's Ria News Agency cited a Syrian airbase worker's comments on the attack on the Shayrat Airfield in Syria.
It came as Russian TV reported that nine planes were destroyed at the time of the hit. All planes are thought to have been out of action at the time.
Images said to have been taken at the Shayrat Airfield showed craters and rubble alongside what appeared to be an aircraft hanger in ruins. The runway, however, is said to have almost completely escaped damage.
