LONDON: A terrorist suspect on trial in London stopped giving evidence on Monday, saying he was worried about the safety of his family in Pakistan if he continued to do so. Omar Khyam, who is accused with six others of plotting a bombing campaign in Britain with more than half a ton of fertiliser explosive, said he had been contacted by the Pakistani Inter-Services Intelligence (ISI). "The ISI in Pakistan has had words with my family relating to what I have been saying about them," he told the court. "I think they are worried I might reveal more about them, so right now, as much as I want to clarify matters, the priority for me has to be the safety of my family, therefore I am going to stop," he added, according to the BBC. In evidence last Thursday, Khyam said he had gone to Pakistan in 2000 to train with ISI, so he could help "free Kashmir", the Himalayan egion claimed by both India and Pakistan. Khyam (24) and six others accused of being a British Al Qaida linked cell were arrested in March 2004 after the fertiliser was discovered in a west London storage depot. Khyam has yet to explain why he allegedly bought it.
