Russia on Friday said that US strikes in Syria have inflicted 'considerable damage' to US-Russia ties.
President Vladimir Putin considers the US strike on a Syrian airbase on Friday as "aggression against a sovereign state," Kremlin spokesman Dmitry Peskov said.
"President Putin considers American strikes on Syria aggression against a sovereign state in violation of international norms, and under an invented pretext," Peskov was reported as saying.
Earlier, Russia, one of the key supporter of the Assad regime in Syria, has "failed in its responsibility" to deliver on a 2013 commitment to secure Syria's chemical weapons, US Secretary of State Rex Tillerson said ahead of his visit to Moscow next week.
Tillerson's visit, the first trip to Russia by a Trump administration official aimed at establishing closer ties with the former Cold War foe, was announced after the US launched cruise missiles against an air base in Syria in retaliation to the chemical weapons attack in Khan Sheikhun in rebel-held Idlib province.
