Russian President Vladimir Putin allegedly told Iranian President Hassan Rouhani that further western strikes on Syria would “inevitably lead to chaos” in world affairs, Reuters reported on Sunday.

“Vladimir Putin, in particular, stressed that if such actions committed in violation of the [United Nations] Charter continue, then it will inevitably lead to chaos in international relations,” the Russian government said in a statement obtained by the news agency.

The statement also noted that both Putin and Rouhani, who reportedly discussed the topic over the phone following the targeted attack on Syrian chemical weapons facilities on Friday, agreed that the strikes had lessened the chances that Syria’s 7-year civil war would be resolved.

Putin’s comments come just after Russian Deputy Foreign Minister Sergei Ryabkov told the nation’s TASS news agency that Moscow would make every effort to improve political relations with the west.

The United States, the United Kingdom, and France conducted a targeted airstrike on three of Syria’s chemical weapons facilities on Friday in response to a suspected poison gas attack earlier this month that killed at least 40 people, including women and children, in the Syrian city of Douma.

President Donald Trump on Saturday called the allied response a “perfectly executed strike,” declaring “Mission Accomplished” on Twitter.

Lt. Gen. Kenneth McKenzie echoed the president's comments during a press briefing at the Pentagon on Saturday, saying he thought the attack had dealt a “severe blow” to the “heart” of the country's chemical weapons program.

U.S. ambassador to the United Nations Nikki Haley said Sunday that the United States would impose new sanctions on Russia to punish the country for its support of Assad and to dissuade the Kremlin from attempts to “cover up” the attack.
