Commenting on reports of a chemical weapons attack in Syria, the British Foreign Secretary William Hague said in a statement today: I am deeply concerned by reports that hundreds of people, including children, have been killed in airstrikes and a chemical weapons attack on rebel-held areas near Damascus. These reports are uncorroborated and we are urgently seeking more information. But it is clear that if they are verified, it would mark a shocking escalation in the use of chemical weapons in Syria. Those who order the use of chemical weapons, and those who use them, should be in no doubt that we will work in every way we can to hold them to account. I call on the Syrian Government to allow immediate access to the area for the UN team currently investigating previous allegations of chemical weapons use. The UK will be raising this incident at the UN Security Council".
