Al-Qaeda plotting attack on Britain - Telegraph
Security was stepped up on Wednesday at British ports, and armed police were put on patrol at the Eurostar terminal at London’s St Pancras station.
They include plans to blow up a passenger jet; Mumbai-style shootings in crowded places; or even hit-and-run attacks using vehicles.
Intelligence has shown that the Syrian arm of a resurgent al-Qaeda is planning similar outrages against the UK, possibly by British jihadists who have already returned from fighting in Syria or Iraq.
