Craig Murray, former British ambassador to Uzbekistan, writes: "The media onslaught has moved past the attack in Salisbury by a “weapon of mass destruction” (quoting Theresa May) which could only be Russian, except that was untrue, and was extremely deadly, except that was untrue too. It now focuses on an attack by chemical weapons in Douma which “could only be” by the Russian-backed Assad regime, except there is no evidence of that either, and indeed neutral verified evidence from Douma is non-existent."
