The partner of a failed suicide bomber was jailed for 15 years Thursday for not telling police about his plans to carry out an attack on the London subway system. Judge Paul Worsley told Yeshi Girma, 32, that it was clear she knew of plans by her partner, Hussain Osman, to set off explosions on the transit system on July 21, 2005. The bombs failed to explode fully and no one was injured. "You could have done much more to prevent the terrorist threat to the public had you revealed what you knew," Worsley said. A jury in London found Girma guilty Wednesday of failing to provide information of the attempted attack, which came two weeks after four suicide bombers killed 52 subway and bus passengers in London. She was also found guilty of assisting an offender and failing to disclose information about his involvement Girma has three children with Osman but had claimed she knew little of what he was doing and that they did not live together. The Crown Prosecution Service said she was his wife. Girma's brother, Esayas Girma, 22, and sister, Mulu Girma, 24, were jailed for ten years each for assisting an offender and failing to disclose information. Worsley said the sentences reflected public condemnation of their actions, and were intended to deter others.
