If Muslim religious leaders around the world will not publicly condemn the taking of children as hostages and their subsequent slaughter — if those "men of faith" will not issue a condemnation without reservations or caveats — then no one need pretend any longer that all religions are equally sound and moral.

An extremist Islamic cleric based in Britain said yesterday that he would support hostage-taking at British schools if carried out by terrorists with a just cause.

Omar Bakri Mohammed, the spiritual leader of the extremist sect al-Muhajiroun, said that holding women and children hostage would be a reasonable course of action for a Muslim who has suffered under British rule.

Mr Mohammed, 44, who lives in Edmonton, north London, but is originally from Syria, also claimed that the Chechen rebels were not responsible for the deaths of more than 350 people - at least half of them children - who are so far known to have died in Beslan.

"The Mujahideen [Chechen rebels] would not have wanted to kill those people, because it is strictly forbidden as a Muslim to deliberately kill women and children. It is the fault of the Russians," he said.
