BRITAIN and the US rushed to accuse Syria of April’s nerve gas attack yesterday after a report avoided blaming any side.

An Organisation for the Prohibition of Chemical Weapons (OPCW) investigation determined the nerve agent sarin was used in the town of Khan Sheikhoun on April 4.

It is leaving a joint UNOPWC probe to determine if President Bashar al-Assad’s government or the al-Qaida-affiliated Hetesh forces occupying the town are to blame.
