From the London Sunday Times:

Islamic terror cells in Britain have been instructed to carry out a series of kidnappings and beheadings of the kind allegedly planned by the nine terrorist suspects arrested in Birmingham last week. The “strategic” assassination instruction was issued by Al-Qaeda’s leaders in Pakistan and Iraq to dozens of their followers in this country. It was uncovered by MI5 last autumn, senior security sources say. As a result police are on standby for multiple attempts by terrorists to kidnap and then behead people across Britain. MI5 is conducting a counter-terrorism surveillance operation to prevent such an attack. The alleged attempt to kidnap and behead a Muslim soldier or soldiers in Birmingham was just the first of a series of planned attacks, security sources say.
