Foreign Secretary Boris Johnson said:

The Organisation for the Prohibition of Chemical Weapons has now confirmed that sarin nerve gas was indeed used in a chemical attack on the town of Khan Sheikhoun in northern Syria on 4 April.

This confirmation cannot be ignored. The UN-OPCW Joint Investigative Mechanism will now work to identify who was responsible. As I have said previously, the UK’s own assessment is that the Assad regime almost certainly carried out this abominable attack.

I urge our international partners to unite behind the need to hold those responsible for this atrocity to account.
