"There is no question there has been an increase in attacks on mosques and Muslims," said Shadjareh.

CAIRO — Videos showing far-right British extremists threatening to behead Muslims in the European country and tear their guts out have been viewed by hundreds and posted on the famous American movies website, YouTube.

The clips show three white British men, wearing black masks and brandishing knives, clubs and weapons, The Sunday Times reported on September 3.

In one video a balaclava-clad man with a Welsh accent tells Muslims to "go home" or risk being burnt alive.

"We are going to rip the life out of you. I am going to tear your guts out. I’ll cut your head off," he said brandishing a foot-long hunting knife with a serrated blade.

The speaker said slaughtering Muslims would remind him of being "back in the Gulf," which the paper said might indicate he served with the British army in the Gulf.

In another video a man with a London accent wonders what should be done to "fight the so-called religion of peace known as Islam."

Noting that the alleged plot to blow up US-bound planes in midair has resulted in "no retaliation" against Muslims, he said: "Well, wake up. I am calling on England, Ulster, Scotland and Wales to stand and defend the island that we love."

Eleven British Muslims have been charged of conspiracy to murder and planning acts of terrorism over the foiled plot while four people were accused of lesser offences.

Five people are still being questioned but have not been charged.

Worrying

The clips, posted between August 11 and 19, were viewed hundreds of time, according to the British paper.

Massoud Shadjareh, chairman of the Islamic Human Rights Commission, said the videoed threats were extremely worrying.

"There is no question there has been an increase in attacks on mosques and Muslims," he told The Sunday Times.

The release of the videos coincides with reports of a rise in the number of attacks on mosques, said the paper.

Islamophobia gained momentum in Britain, especially after the alleged terror plot.

British Muslims, estimated at 1.8 million, reacted angrily at government plans to single out passengers at airports for security checks based on ethnicity and religion, saying that such a "terror profile" mounted to racism.

Following attacks on London's underground network in July 2005 that left 56 dead, the Muslim minority felt under siege and attacks on mosques have been on the rise.

Attacks and discrimination made two-third of British Muslims consider leaving the country.

Gerry Gable, publisher of the anti-fascist magazine Searchlight, said the anti-Muslim threats must be taken seriously.

"Currently there is a campaign by members of parliament to shut down Nazi websites, so it is very disheartening to find a reputable company like YouTube.com playing host to people advocating terrorism."
