ITV News has been given exclusive access to a tape recording in which a radical Muslim cleric talks about flying a plane into Downing Street. Shiekh Omar Bakri Mohammed - who is based in Britain - talks of suicide bombings and says that an attack on No 10 would be reconcilable with the Muslim faith. He also claims that missions of "self sacrifice" and "martyrdom" would be welcomed by Allah. It is a statement that will horrify and disgust people across Britain, but he made these statements without any fear of prosecution. On the tape he was heard to say: "You want to call us extremist, yes I am extreme. Somebody he fly aeroplane and he decide to fly the aeroplane over 10 Downing Street.... It's another self-sacrifice operation... What people call suicide operations they mean somebody he wear explosives or he carries explosives and he go and he blow it in the building with the people... Martyrdom is what you want. Make sure you have nothing left behind you to think about or cry for and fight in the name of Allah."
