More details are emerging about the people involved in last Saturday's attack on the airport in Glasgow, Scotland, and last Friday's failed car-bombing attempts in London. But some of the information is conflicting.

As of late Tuesday morning, at least eight people had been arrested in connection with the two incidents. The British Broadcasting Corporation reports that all of the suspects are linked to Britain's National Health Service.

According to the BBC, the suspects include an Iraqi doctor; a Jordanian doctor from a Palestinian family and his wife, who worked as a lab technician; and an Indian national who was arrested in Australia Monday, after trying to board a flight to India with a one-way ticket. Several media reports say the Indian doctor had worked in Britain before he moved to Australia last year.

A fifth suspect who was arrested in Liverpool Saturday night is also a doctor from India, according to the BBC. Media reports have linked him directly to the doctor arrested in Australia.

Two other suspects are said to be medical students, although the BBC says that has not been confirmed. And the eighth suspect remains hospitalized in Glasgow, with severe burns. He's believed to be the man who crashed a flaming Jeep Cherokee into the main terminal at the Glasgow Airport on Saturday.

Last weekend, Britain's new prime minister, Gordon Brown, linked the attacks to al-Qaeda. And CBS News reports that according to its sources, the suspects were recruited in 2004 and 2005 by Abu Hamza al-Muhajir, the current leader of al-Qaeda in Iraq. Al-Qaeda is the Muslim group that executed the attacks on New York City's World Trade Center and the Pentagon, outside Washington, DC, on September 11, 2001.

According to CBS News, al-Muhajir recruited the suspects because they could easily move into Western countries, assimilate and law low until the time came to attack. CBS says Britain has a "fast-track" program for foreign medical students who want to get into the country. Therefore, it would have been relatively easy to get the suspects in.

However, according to the New York Times, law enforcement officials in Britain and the United States said Monday they'd found no link between the suspects and al-Qaeda up to that point. A man the Times describes as a "senior Western law enforcement official" also said there was "no indication of any outside direction," and "no connection to the United States whatsoever."

There may be more arrests in connection with these incidents. But according to the Times, one Western official said British authorities were "pretty confident" they had rounded up the people behind the plot.
