London ? A Jordanian doctor has been charged in connection with foiled car bomb plots in London and Glasgow, Scotland, police said Thursday.

Mohammed Jamil Asha, 26, was charged with conspiracy to cause explosions, a police spokeswoman said. Asha was detained June 30 on a northern England highway. His wife, Marwa Asha, was arrested on the same date but later released.

Asha is the fourth person to be charged since a pair of cars packed with gas cylinders and nails were found June 29 in central London. The next day, two men crashed a flaming Jeep Cherokee loaded with gas canisters and gasoline into security barriers at Glasgow airport’s main terminal.

Asha will appear today in a London court.

Others charged in the plot are Bilal Abdullah, an Iraqi who worked in a hospital outside Glasgow and who was a passenger in the car that was driven into the airport terminal building; Sabeel Ahmed, 26, who worked in a hospital outside Glasgow; and Mohammed Haneef, 27, formerly of Liverpool but who took a job at an Australian hospital a year ago.
