Al-Qaida elements fighting with rebels in Syria constitute the most serious terrorist threat to Britain, and if they were to get their hands on Syria's chemical weapons the consequences could be catastrophic, according to British spymasters.
The warnings, in the latest annual report of the parliamentary intelligence and security committee (ISC) published on Wednesday, come amid growing reports that Syrian rebels are trying to acquire chemical weapons.
Russia said on Wednesday it had proof Syrian rebels used the nerve agent sarin in a missile attack on a government-controlled suburb of Aleppo in March. The British prime minister, David Cameron, said last month that al-Qaida-linked elements in the rebel movement had tried to capture chemical weapons for probable use in Syria.
