US Secretary of State Rex Tillerson has criticised Russia, saying it had failed to prevent Syria from carrying out a chemical attack on a rebel‑held town.
He said Russia had agreed to ensure Syria's chemical weapons stockpiles were destroyed ‑ and its failure to do this enabled the attack.
The US fired 59 missiles at a Syrian airbase after the alleged attack.
Syria has denied using any chemical agents and Russia says the US gave no evidence Syria has chemical weapons.
Russia is the Syrian government's main ally, and helped facilitate a 2013 agreement to destroy Syria's chemical arsenal.
The suspected chemical attack on Tuesday left 89 people dead.
