Suspects in Britain Bomb Plot Linked by Family, School, Work

Two other men, ages 28 and 25, who lived in doctor's residences at Royal Alexandra Hospital have also been arrested.

Abdulla "was certainly very angry about what was happening in Iraq. He supported the insurgency. He loudly cheered the deaths of British and American troops," an acquaintance, Shiraz Maher, told the BBC. "But to say it was just all about Iraq or foreign policy is mistaken. It feeds off a much wider ideological infrastructure." Maher is a former member of Hizb ut-Tahir, an Islamic group often accused of inciting violence.

Maher said Abdulla once showed a Muslim roommate a video of a beheading, warning him the same thing could happen to him if he were not more committed to his faith.

Abdulla lived in a comfortable two-story home on a pleasant street in a Glasgow suburb, where investigators now suspect he and Ahmed may have assembled bombs. Neighbors said they rarely saw the occupants of the house, although one neighbor said she saw a man washing a Jeep Cherokee there on Saturday morning, a few hours before the airport attack. The neighbor said she thought that was odd, because it was raining.

"People are shocked. Doctors, consultants and surgeons live around here," said Jeff Heath, who works at Paul's fish and chip shop near Abdulla's home. "But I guess that makes it an ideal place to hide."

Six hours after the airport attack, police staged a dramatic arrest on a highway in central England. At least five unmarked police cars forced a car off the road and arrested its occupants, Mohammed Asha, 26, a doctor working at a Staffordshire hospital, and his wife, Marwah Dana Asha, 27, a former hospital lab technician.

Records show that Asha earned his medical degree in Jordan in 2004 and began practicing in Britain in March 2005. He was described as a brilliant student and newspaper photos showed him meeting Jordan's Queen Noor, a patron of the school he attended.

Several of the suspects seemed to know each other from Cambridge. Maher said that when he lived in Cambridge in 2005, he knew Kafeel Ahmed and Abdulla. Asha also worked at a Cambridge hospital.

Officials in the United States said Asha was one of the two who inquired about applying for medical training positions in the United States within the past year, but did not pursue the application.

On Saturday in Glasgow, a week after the airport attacks and on the two-year anniversary of suicide attacks on the London public transit system that killed 52 passengers and wounded more than 700 others, about 1,500 people, many of them Muslim, held an anti-terrorism rally in downtown Glasgow.

"Let us be clear, no one, no one wants to beat these terrorists more than the Muslim community," said Osama Saeed, spokesman in Scotland for the Muslim Association of Britain.
