A jury has found three men guilty of plotting to blow up transatlantic planes using home-made liquid bombs. Islamic extremist Abdulla Ahmed Ali, 28, from Walthamstow, was found guilty of conspiring to murder thousands of people in an unprecedented plot. He was the leader of an east London al Qaida-inspired terror cell. Assad Sawar, 29, of Walton Drive, High Wycombe and Tanvir Hussain, 28, of Nottingham Road, Leyton, have also also been found guilty of the same charge. However Ibrahim Savant, 28, of Denver Road, Stoke Newington, Arafat Waheed Khan, 28, of Farnan Avenue, Walthamstow, Waheed Zaman, 25, of Queen's Road, Walthamstow, were found not guilty of the airliner plot. The jury failed to reach a verdict on Umar Islam, 31, of Bushey Road, Plaistow, regarding the airliner plot, while he was convicted of conspiracy to murder. Donald Stewart-Whyte, 23, of Hepplewhite Close, High Wycombe, has been acquitted on all charges. The arrest of the gang in August 2006 sparked tight restrictions on carrying liquids on to aircraft that led to travel chaos. With thousands killed in the air and on the ground, the explosions would have exceeded the carnage of the September 11 attacks. Counter terrorist police, the security services and prosecutors spent more than £35 million foiling the plot and bringing Ali to justice. The arrest of the gang in August 2006 sparked tight restrictions on carrying liquids on to aircraft that led to travel chaos. It will also be seen as a vindication of the decision to retry Ali after he was found guilty of conspiracy to cause explosions last September. The previous jury failed to reach verdicts on the airline plot.
