London ? Prime Minister Tony Blair said Tuesday that Britain would not “give one inch” to terrorists on his policy on Iraq and the Middle East, while police said two suspects in last week’s failed bombings were emigrants from Somalia and Eritrea.

Blair made his comments after a rare meeting with opposition party leaders to discuss new anti-terror legislation aimed at preventing a repeat of the July 7 suicide bombings that killed 56 people, including four attackers.

The opposition, however, had reservations about increasing the time to hold such suspects, saying it could erode civil liberties.

At his monthly news conference, Blair said the response by Londoners to the July 7 bombings and the failed July 21 attacks against identical targets had been “magnificent.”

“London is being tested but standing firm,” he said.

Asked whether the British-backed and U.S.-led invasion of Iraq had fueled terrorist attacks around the world and in London, Blair said “there was no excuse or justification” for their actions of the bombers.

“Whatever excuse or justification these people use, I do not believe we should give one inch to them, not in this country and the way we live our lives here, not in Iraq, not in Afghanistan, not in our support for two states, Israel and Palestine, not in our support for the alliances we choose including with America. Not one inch should we give to these people,” Blair said.

A British police forensic expert in protective clothing walks up the side of a suspect car found Tuesday in London. Police believe the car could be connected to Thursday's failed bombings.

“Sept. 11 for me was a wake-up call,” he said. “Do you know what I think the problem is? A lot of the world woke up for a short time and then turned over and went back to sleep again.”

But a new poll showed that a majority of British Muslims surveyed believe Blair’s decision to join the U.S.-led war in Iraq was one of the reasons behind the bombings.

The ICM poll for The Guardian newspaper said 58 percent of British Muslims responding agreed “a lot” with the suggestion that the decision to join the invasion of Iraq was a reason for the attacks, while 21 percent agreed with the statement that the war was “a little” bit responsible, and 10 percent said it had nothing to do with the bombings.

Muslims consider leaving

The poll also said about two-thirds of Muslims surveyed after the bombings said they had thought about moving away from Britain.

It said 63 percent of Muslims asked said they had considered whether they wanted to keep living in Britain. Older Muslims were more concerned about staying, with 67 percent of those over 35 saying they had thought about moving away.

One in five British Muslims said they or a family member had faced abuse or hostility since the July 7 attacks, according to the poll.

Closed-circuit surveillance cameras keep watch in central London on Tuesday. Thousands of CCTV cameras watch the subway system alone, and investigators have used the footage to identify the attackers following the series of explosions in the city's transportation network earlier this month.

The ICM poll interviewed a random sample of 500 Muslims by telephone July 15-19. No margin of error was given.

The Home Office said one of the suspects in the July 21 bombings, Yasin Hassan Omar, 24, had arrived in Britain in 1992 from Somalia. He is suspected of trying to blow up a subway train near Warren Street station.

Muktar Said Ibrahim, also known as Muktar Mohammed Said, 27, who is suspected of trying to bomb a bus, is a naturalized British citizen who arrived from Eritrea in 1992, the Home Office said.

Both men came as dependents of refugees.

Police explosives experts were examining suspicious material found Tuesday in a north London apartment connected to both Omar and Said, and a police spokeswoman said a car had been impounded nearby.

A spokeswoman for the London borough, the Enfield Council, told The Associated Press that Omar had been the registered tenant in the apartment since 1999, receiving $130 in government housing benefits until May.

Police also were questioning five people arrested in connection with the July 21 attacks.

The bombs, which failed to fully detonate, were stored in clear plastic food containers and put into dark-colored bags or backpacks. Peter Clarke, head of the Metropolitan Police anti-terrorist squad, said those four bombs were similar to another found abandoned in a park Saturday, raising fears a fifth bomber was on the loose.
