Eight arrested as fast-paced terror probe widens

LONDON, England (CNN) -- Police in Britain are combing through evidence in an international search for more suspected terrorists with ties to the attempted attacks in London and Glasgow.

Police have conducted at least 19 raids and arrested eight people, including two foreign-trained doctors from Jordan and Iraq.

The most recent arrest was in Brisbane, Australia, where a 27-year-old man -- identified by Scotland Yard only as "H" -- was detained at the Brisbane Airport, according to Premier of the state of Queensland Peter Beattie.

Australian Attorney General Philip Ruddock said "H" was a doctor who had been working as a registrar at a Queensland hospital. Ruddock would not disclose his nationality, but he did say the man was not Australian.

Australian police were executing search warrants at locations in the Brisbane area, Beattie said.

An Iraqi doctor has been identified as one of the two men who rammed an explosives-laden SUV into a terminal at Glasgow International Airport in Scotland on Saturday.

Police think the doctor, 27-year-old Bilal Abdulla, worked at Royal Alexandra Hospital near Glasgow.

The other man in the Glasgow attack remains in critical condition at that hospital, a hospital spokesman said. The suspect, whose name has not been released, set himself on fire after he jumped from the burning vehicle. A witness said the suspect was "covered head-to-toe" in flames.

British authorities believe at least one of those men was involved in planting two car bombs in central London on Friday. The cars, packed with fuel and nails, could have killed hundreds if they had been set off.

Police on Sunday arrested two more suspects at the Royal Alexandra Hospital. They were identified only as men ages 28 and 25 who are not believed to be of Scottish origin. They were arrested while police searched the doctors' quarters at the hospital. Police have not said if those men are doctors.

Doctor arrested after being cornered on highway

Late Saturday, police cornered and arrested Dr. Mohammed Asha and his wife along a highway in the northern English county of Cheshire.

Asha is Jordanian-educated physician who moved to England with his family two years ago, according to British media reports and a source in Jordan.

Asha's family in Amman, Jordan, is distraught and has not heard anything from the British Embassy or from London, his older brother, Ahmed Asha, said.

The family is especially worried about Asha's 2-year-old son, who was born in Britain shortly after the couple moved there. The family does not know who is taking care of the young boy since both parents have been arrested, the brother said.

His father in Jordan said there said there was no way he son was involved.

"I'm sure of it," he said. "Not only because I am his father, but because Mohammed was coming back here after specializing in Britain."

Asha is believed to work at the North Staffordshire Hospital, near the Midlands town of Newcastle-under-Lyme, where police searched a house on Sunday. The hospital refused to comment.

It is unclear if police have arrested another doctor and his wife, who live just two miles from Asha. Their house was sealed and searched by police in Newcastle-under-Lyme, Staffordshire.

The doctor and his wife have lived there for about a year, neighbors said.

On Sunday, a 26-year-old man was arrested in Liverpool after police found a suspicious car at the airport, Merseyside police said. Police raided two locations in the Liverpool area after he was arrested.

In Washington, U.S. Homeland Security Secretary Michael Chertoff said on CNN's "Late Edition" it is too early to tell who is behind the attack, but it is "a reasonable possibility" that it may be an al Qaeda-linked group. E-mail to a friend
