Muslims fear backlash after UK soldier's killing

Former jihadist calls attack 'cowardly'

(CNN) -- Fears were growing in Britain Monday of a surge in Islamophobia in the wake of the knifing death of a British soldier last week that his suspected attackers claimed was revenge for the deaths of Muslims worldwide.

Officers arrested two men in the town of Grimsby on England's east coast on suspicion of arson after a mosque was set on fire, according to Humberside county police. No one was injured in the blaze.

The anti-Muslim English Defence League demonstrated in the town's center the morning before the fire. It will launch another march Monday near the office of Prime Minister David Cameron.

Enraged by the murder of British soldier Lee Rigby in the southeast London neighborhood of Woolwich Wednesday, the EDL has called for marches around the UK.

In a demonstration in Newcastle on Saturday, angry supporters cried out for Muslims to leave the country. EDL demonstrators threw objects at counter demonstrators, and police stepped in to keep the raucous men from going after their opponents.

The EDL claims Islamic law is poised to overthrow British society and calls for Britons to act aggressively to preempt it.

"If we fail to show courage now, we will leave revolution, civil war or subjugation to our children and our children's children," reads the motto on the EDL's website. "Any act of muslim extremism will now be countered by the EDL," it vows on its Facebook page.

Fear at the mosque

On Friday members of the Grimsby Islamic Cultural Centre expressed fear on its Facebook page over the EDL's announcement of Saturday's protest.

"Guys can you try to keep as safe as poss as the EDL in Grimsby have planned a few demonstrations in the coming days," Nadia Hussein posted.

Another poster on the mosque's Facebook page claimed the Grimsby EDL gave out the Islamic center's address. "Stay safe and Allah be with us all," Gayle Hardy added.

CNN could not corroborate the claim on EDL Grimsby's Facebook page. Police have not implicated the EDL or any other group in the mosque fire.

After the blaze, police said they were aware of online postings "by a small minority of individuals" that were intended to "incite trouble," Humberside County police said.

"Those people should be aware that we are monitoring these sites in Humberside and we will take action against those intent on attempting to incite violence or post messages of a racial nature," police warned.

Reports of anti-Islamic incidents surged after Rigby's gruesome killing, according to Fiyaz Mughal, who operates a hotline for Muslims under attack. In the 48 hours after the murder, he received 162 reports from victims saying people had called them names, assaulted them or thrown things at them.

Before the Woolwich killing, Mughal received around five complaints per day.

Eight mosques were attacked across the country during that time, he said.

The EDL

The EDL sports symbolism that resembles that of neo-fascist groups. Its logo is adorned with red medieval crosses. One of its popular slogans is "Defender of Faith! Defender of England!" A motif on some of its sweat shirts is the image of a Christian knight, possibly a Crusader, praying with his sword drawn.

Many EDL sympathizers seen at demonstrations have similar appearances to those of right-wing extremist groups. Almost all of them are young, white men. Many of them have shaved heads typical of skinheads and wear nationalist symbols.

But the group focuses strictly on Islamophobia. It claims to oppose racism and to promote democracy and diversity. It brags that it has support from gay rights groups, Sikhs and Hindus.

The EDL even links to a "Jewish Division" on its Facebook page and posts messages of support for people of color it feels have fallen victim to Islamist extremists.

Members of the EDL clashed with police near the scene of Ribgy's killing last week. A tweet from its official account proclaimed then that "it's fair to say that finally the country is waking up!:-) NO SURRENDER!"

Murder sparked outrage

Men in a blue car drove up on a sidewalk Wednesday and struck the 25-year-old Rigby. The alleged killers got out of the car, according to police, then stabbed and slashed him to death with knives and meat cleavers, before dragging his body into the middle of the street.

After the attack, one of the men, his right hand covered in blood, the left brandishing a knife and a cleaver, found someone with a camera and talked into it. He justified the terrible deed as revenge for the killings of Muslims around the world.

The video went viral on the Internet.

When police arrived, one of the suspects rushed officers with a gun, authorities said. Police opened fire, wounding both of them.

Nine arrests were made in the case. Three are still in custody, including the two wounded men. Two were released without charge, and four were released on bail.

Extremism task force

Britain is forming a task force that will examine the dynamics behind extremist groups in the country, Prime Minister David Cameron's office announced Sunday.

The group, led by Cameron, will "have a general focus on extremist groups, but accept that in practice the greatest threat is from Islamist extremists," a statement from Downing Street said.

The Muslim Council of Britain said the task force needs to look at "extremism from all quarters" while forming an effective strategy.

"We must be vigilant and ensure we do not inadvertently give into the demands of all extremists: making our society less free, divided and suspicious of each other, said a statement from the council's secretary-general, Farooq Murad. Lessons from the past indicate that policies and measures taken in haste can exacerbate extremism."

Rigby's slaying near the Royal Artillery Barracks in the working-class neighborhood shocked people across the United Kingdom.
