LONDON , England ( CNN ) -- Two men accused of failed car bomb attacks in London and a car bombing at Glasgow International Airport last year went on trial Thursday . Mohammed Asha , a doctor , is accused of conspiracy to murder and cause explosions . Bilal Abdulla and Mohammed Asha , both doctors , are charged with conspiracy to murder and conspiracy to cause explosions . Their trial at London 's Woolwich Crown Court is expected to last up to 12 weeks . The case stems from the discovery in June 2007 of two explosives-filled Mercedes sedans in central London . One of the cars was parked across the street from a packed nightclub near Piccadilly Circus and the other was towed from an underground car park at Hyde Park . An ambulance crew notified police about the first car after they saw smoke coming from it . The second car was towed for a parking offense but drew suspicion because it smelled of gasoline . Officials said both cars cars were filled with fuel , gas canisters , and nails . Police managed to defuse them . The following day , with attention still focused on the averted attacks in the capital , a Jeep sped through the barriers outside Glasgow International Airport and slammed head on into the terminal . The Jeep , filled with propane gas , burst into flames and created a fireball . The driver and passenger jumped out of the car . One set himself on fire and later died in the hospital ; the other was identified as Abdulla , an Iraqi doctor who had been practicing medicine in Scotland . Later that day , police arrested Asha as he was driving with his wife on a highway in Cheshire , England . Police said Asha , a doctor of Palestinian descent who grew up in Jordan , conspired with Abdulla to carry out the explosions . The incidents happened just days after British Prime Minister Gordon Brown took office . A third man charged in the case , Sabeel Ahmed , pleaded guilty in April to failing to disclose information about an act of terrorism . He was ordered to be deported to India .
Men accused of failed car bomb attacks in London and Birmingham put on trial . Bilal Abdulla and Mohammed Ali charged with conspiracy to murder . The men , both doctors , also charged with conspiracy to cause explosions .
