A woman is comforted Saturday as she waits to lay a bouquet of flowers in a memorial garden outside King's Cross Station in London to mark the second anniversary of the London bombings. The suicide bombings killed 52 people.

LONDON — Britain marked the second anniversary Saturday of the London suicide bombings that killed 52 people, a grim reminder as the country confronted a new wave of terrorism and an Iraqi doctor appeared in court on charges linked to the most recent foiled attacks.

Bilal Abdullah — a 27-year-old doctor born in Britain and raised in Iraq — appeared in a London court amid tight security after he and another man allegedly crashed a gas-laden Jeep Cherokee outside the main terminal of Scotland's largest airport.

Charged with conspiring to cause explosions, he is one of eight suspects accused in foiled car bomb attacks in London and Glasgow a week ago. Speaking only to confirm his name and birth date, Abdullah is scheduled for his next court appearance on July 27.

Two cars packed with gas cylinders and nails were discovered in London — one outside a crowded nightclub, the other near Trafalgar Square. The Jeep Cherokee smashed into the security barriers at Glasgow airport.

Police added patrols around the capital where the first leg of the Tour de France cycle race was taking place Saturday, along with the July 7 bombing anniversary, the Wimbledon tennis tournament, and a Live Earth concert starring Madonna.

"It's amazing that it was two years ago," said John Salding, 63, whose girlfriend was among the 52 people killed in the 2005 suicide bombings. "My memories are all so fresh."

Prime Minister Gordon Brown and other government ministers left wreaths at the King's Cross subway station for a somber remembrance of the bombings.

The four suicide bombers struck three underground trains and one double-decker bus in 2005, killing 52 people and themselves in an attack with a trail leading back to al-Qaida training camps in Pakistan. More than 700 people were injured in the rush-hour attack.

Counterterrorism agents have foiled several attacks since then in Britain — the trans-Atlantic airliner plot last August where a group planned to blow up as many as 10 airplanes, and the most recent failed car bomb attacks in London and Glasgow.

Besides Abdullah, seven other suspects remain in custody in the latest foiled attacks, including a man hospitalized in critical condition in Scotland with severe burns.

Two of the suspects made inquiries about working in the United States, the FBI said Friday.

An FBI spokeswoman said Mohammed Asha and another suspect had contacted the Philadelphia-based Educational Commission for Foreign Medical Graduates.

Asha, a Jordanian physician of Palestinian heritage, contacted the agency within the last year, but apparently did not take the test for foreign medical school graduates, said the spokeswoman, Nancy O'Dowd.

Most of the suspects worked for Britain's health service. They come from countries in the Middle East and India. Seven of the suspects are being held in Britain and one in Australia.
