"When you live in this country, you know it is not worth living," said the stocky one with thick black hair blowing up to his chest. "A man, a Muslim cannot live in this country; it is an immoral place. That is why we need to change it."

Others nodded in agreement.

"That is why the slap came," the man said. "7/7 was a slap for the Kafirs. How many slaps they gave us? Now we gave them one slap. What do you do when someone slaps you? You also slap back." And then he utters some Arabic verses and translates them: "It is blood for blood, eye for eye."

As they turn and pass Lutton's Madina Mosque, they glance at the prayer house hatefully and the fair one says: "Muslims have become derailed, they don't follow the true teachings of Islam. They have forgotten Jihad. They just lick the foot of the Christians."

The three belong to the group of Al Muhajeeroon now renamed Al Gharib, the extremist Islamic group in Britain set up by Syrian born radical Islamist Sheikh Omar bin Bakri Muhammad whom the British government wants to deport for spreading religious hate.

On July 22, barely two weeks after the London attacks, Bakri said militant Islamists will continue to attack Britain until the government pulls its troops out of Iraq and Afghanistan.

And these three two Bangladeshis and one Pakistani are his followers in Lutton, a small town outside London. It is here that the 7/7 bombers had met briefly at the station before finally going ahead with their deadly mission. It is here that the police recovered a rented car stocked with explosives.

In this crime prone town of Lutton, where ghettos abound, Al Muhajeeroon has been active among the youth, residents say, indoctrinating them with the idea of Jihad. Over the years, this group has mushroomed in Britain and even in London they are seen preaching their ideas in Whitechapel and Brick Lane. But since 7/7, they simply vanished from London; even on Fridays, a day they usually prefer to hand out their flyers at the mosque corners, they could not be seen. But here in Lutton, there they were.

One of the Lutton residents who knows these youths from their early age said they grew up as any other lad: they used to have fun, play cricket, dress up smartly in the latest designs and go to mosques on Fridays.

"They had good jobs at the council, one of them even had a BMW," said the resident. "He must have been earning at least 22,000 pounds a year. Then suddenly they started to change."

They started doing this group, left their jobs, and grew beards. They started talking of Jihad and the West's policy on the Middle East.

"I was in the path of the Satan," said the thickly bearded youth. "Then I got to know Allah's way and that is what I have been working for."

"No, I don't belong to this society. You tell me if anyone can integrate with this immoral society of sex and drugs," says the other one with a wavy beard and long hair. He looks more like an Afghani. "I am not a Bangladeshi, I am not a British, I am not a Bangali. My identity is I am a Muslim. And I must fight on for Islam."

"I am here because this country belongs to nobody," he says. "It is Allah's land. Even my body is not mine, it is Allah's and whatever He wishes my body will be used for that purpose."

"As a true Muslim, it is my duty to ensure that Islam is established all over the world," said the Pakistan born. All the three have their British passport though.

And they don't want to do it through elections, as they campaigned in the last polls that any voting is Haram and anyone to vote will become a Kafir. They even tried to beat up a Labour MP at Lutton in the last elections before the police rescued her.

In London, Deputy Secretary General of the Muslim Council of Great Britain Dr Muhammad Abdul Bari named two groups Al Muhajeeroon or Al Gharib and Hizbut Tahiri as the two extremist organizations operating in Britain. He also said a number of reasons might have led the terrorists to bomb the London Underground and these include their anger against British foreign policy and hate preaching by extremist groups.

"The injustices done in Iraq and other places are frustrating the people here," Bari told The Daily Star. "We don't condone bombing for that reason, but these work as oxygen for terrorist ideas. Bombing is killing the innocent. One has to go to the root causes of creating the terrorists. We want to get as much information as possible about why these things are happening."

Zillur Rahman, a Hizbut Tahiri member in Lutton, however denied having any link to extremists.

"Islam does not target the innocent," he said. "Jihad is against the armed persons. We need to look at the whole issue of bombing, including what is happening around, not at one thing in isolation."

And as Britain grapples with the riddle of why many young Muslims are embracing the radical ideals, it has been pointed out that these people come mainly from the rundown areas, living in ghettos in isolation from mainstream society.

"It is the poverty, inability to mix with the mainstream that makes them frustrated," said Ansar Uddin Ahmed, a Bangladesh born British in London. "I have seen these so called Jihadis in my areas. They usually come from the poorest families and get sucked up easily by the hate preachers. If Britain has to stop this, the economic situation of the Muslims has to be improved."
