Russian President Vladimir Putin called the US air strike on Syria as an aggression against a sovereign state and demanded an emergency meeting of the UN Security Council to discuss the strike against ally Bashar al-Assad's forces in Syria.
"We call upon the UN Security Council to hold an extraordinary meeting to discuss the situation," the foreign ministry in Moscow said in a statement, calling the strike a"gross... violation of international law."
Moscow also announced that it is halting an agreement with the United States aimed at avoiding clashes between their forces in the skies over Syria in response toWashington's strike in the war-torn country.
"The Russian side is halting the effect of the memorandum for prevention of incidents and ensuring the safety of air flights during operations in Syria which was agreed with the US," a statement by the Russian foreign ministry said.
Following the US air strike on a Syrian airbase, Turkey called for a no-fly zone in Syria.
"In order to prevent similar massacres from happening again, it is necessary to enforce a no-fly zone and create safe zones in Syria without further delay," Turkish PresidentRecep Tayyip Erdogan's spokesman Ibrahim Kalin said in a statement.
