Responding to the US decision, Foreign Secretary Boris Johnson said:
The UK welcomes US action to sanction individuals connected to the use of chemical weapons in Syria. The abhorrent attack on Khan Sheikhoun is a stark reminder that the international community must work together to deter the future use of chemical weapons in any circumstances.
Sanctions send a clear signal that actions have consequences and seek to deter others from a similar acts of barbarism. We welcome the role sanctions play in increasing pressure on the Syrian regime to turn away from its military campaign.
We will continue our efforts to hold accountable those responsible for chemical attacks, including through the UN and EU, and to energise international support for the UN-led political process. Only a political settlement will bring an end to the war in Syria.
