Scotland Yard said the investigation into the alleged plot had recovered chemicals that could be turned into explosives, equipment to make bombs, suicide video notes from some accused of involvement in the plot, and a manual on making explosives.
Eight men have been accused of planning to “manufacture and smuggle the component parts of improvised explosive devices on to aircraft and assemble and detonate them on board,” said Susan Hemming, the head of counter-terrorism at the Crown Prosecution Service.
The men are charged with two offences of conspiracy to murder, and with the new offence of preparing acts of terrorism, which became law after the attacks on London’s transport network on July 7 last year.
Three others have been charged with other terrorism offences: one of possessing items useful for terrorism, and two, including Cossar Ali, 23, of failing to tell the police about what she is alleged to have known about terrorism.
Mrs Ali’s seven-month-old child will be cared for by relatives, it is believed. Her husband, Ahmed Abdullah Ali, is charged with conspiracy to murder.
