Britain marked the second anniversary of the terrorist attacks on the London transit system.

Explosions in three underground trains and a bus during the rush hour on July 7, 2005, killed 52 people and injured more than 700 others.

Prime Minister Gordon Brown and other British officials laid wreaths Saturday at the scene of one of the 2005 bombings, the Kings Cross underground station, in a low-key ceremony.

FIRST SUSPECT IN COURT OVER GLASGOW ATTACK

Also in London, the first person charged in connection with three failed car bombings in London and Glasgow appeared in court.

Iraqi doctor Bilal Abdullah, 27, who is one of two men who drove a flaming vehicle into the terminal at Glasgow Airport, is charged with conspiring to cause explosions.

His lawyers did not seek bail, and judge Anthony Evans ordered Abdullah held at a high-security prison until his next hearing at London's Central Criminal Court on July 27.

Prosecutors suspect Abdullah and Kafeel Ahmed, believed to be the driver of the Jeep, carried out the attempted bombings in London before returning to Scotland — where Abdullah worked at a Glasgow-area hospital — and attacking the airport.

Abdullah is one of eight Muslim medical professionals arrested over the foiled car bomb attacks in London and Glasgow a week ago.

Britain is still on a "severe" level terrorism alert, down from the highest "critical" level.
