Yeshi Girma is the mother of Osman's three children
The wife of attempted 21 July bomber Hussain Osman has been jailed for 15 years for failing to tell police about his plot to attack London.
The Old Bailey heard that Yeshi Girma, 32, of Stockwell, south London, knew of Osman's plan to set off a bomb at Shepherd's Bush Tube station.
Yeshi had helped him escape from London to Brighton, the court was told.
Her brother Esayas Girma, 22, and sister Mulu Girma, 24, who also aided Osman, were jailed for 10 years.
Mohamed Kabashi, 25, from Brighton, Mulu's boyfriend, was jailed for nine years after he admitted assisting Osman and failing to disclose information.
After his bomb failed to explode, Osman went on the run, taking a Eurostar train to Paris and then travelling to Italy, where he was captured.
The court heard how Girma had helped him to escape, taking him to Mulu's flat in Brighton and giving him money and a mobile phone.
Mohamed Kabashi, Mulu Girma and Esayas Girma were all jailed
Just over 30 minutes after his attempted attack, Osman was talking to his wife on the phone planning a way to flee.
Prosecutors said she had also been aware of the suicide-bomb plot beforehand, having been with Osman when the final preparations had been made, and had failed to go to the police with what she knew.
Judge Paul Worsley told Yeshi: "You already shared Osman's extreme views on Islam and co-ordinated the escape plan for the father of your three children after he failed to achieve his sought-after place in paradise."
Esayas, of Stockwell, south London, Yeshi and Mulu had all been found guilty of assisting an offender and failing to disclose information about Osman's part in the 21 July plot.
During the hearing, Yeshi sobbed. She raised her hands in the air when she was sentenced.
She had to be helped as she was taken down from the dock.
Jurors were told that Yeshi had known that her husband had been radicalised, and had allowed him to take their young son away to a training camp in Cumbria, where he had met four of the five other 21 July plotters.
Her fingerprints were found on tapes of radicals, including cleric Abu Hamza al-Masri, carrying out "extremist Islamic preaching".
Pavlos Panayi, defending Yeshi, said: "Her actions were instigated by a twisted and irrational devotion to Osman, the father of her children, with whom she had had a long, troubled and volatile relationship."
In July 2007 Osman and three other men were jailed for life for the failed attacks.
