LONDON - Three British Pakistanis accused of plotting a series of suicide attacks on transatlantic jets on Monday pleaded guilty to conspiring to cause explosions. Abdullah Ahmed Ali, 27, Assad Sarwar, 28, and Tanvir Hussain, 27, admitted the offence at Woolwich Crown Court, in southeast London. But they denied that their bombs were part of a wave of suicide attacks on US-bound passenger jets as they used homemade devices made of hydrogen peroxide smuggled on board in Lucozade and Oasis soft drinks bottles. Instead they claimed that they were only planning to set off small devices around London to protest against UK foreign policy and had no intention to kill or cause injuries. The three men listed Houses of Parliament, Heathrow Terminal Three, other 'iconic' buildings or sites like oil refineries as their potential targets. The jury must now decide whether they - and five other defendants - are guilty of conspiracy to murder. The charges the men face have been amended. All eight men deny two charges of conspiracy to murder between January 1 and August 11, 2006. One of the charges specifies that the attacks would involve the detonation of improvised bombs on passenger aircraft. Prosecutors claim the eight men plotted to blow up passenger jets flying from Heathrow to major cities in North America. They planned to use powerful hydrogen peroxide liquid bombs disguised as soft drinks to bypass airport security, jurors were told. The devices would be assembled by injecting the chemicals into plastic soft drinks bottles and detonated by using a battery from a camera flash, it was claimed. They were being assembled at a bomb factory flat bought by the gang for cash in Forest Road, Walthamstow, northeast London, the court heard. The same flat was used by six members of the gang to record martyrdom videos in which they ranted hatred against the West and non-Muslims, jurors were told. Peter Wright QC, prosecutor, said the gang were "not long off" executing their plan when counter-terrorism police swooped in August 2006.  He said Ali, the alleged ringleader of the plot, was caught with a blueprint for the operation recorded in a pocket diary and on a computer memory stick. Stashes of hydrogen peroxide and other bomb-making equipment were found hidden at Sarwar's home and in woodland nearby, the court heard. In their defence, Ali and Sarwar said they planned to record a documentary highlighting injustices against Muslims in Iraq, Afghanistan and Lebanon. A small explosion at the Houses of Parliament in which no one was going to be hurt would act as a publicity stunt to draw attention to the programme. The two men also considered other targets including gas terminals, oil refineries and airports, the prosecution claimed. Ali and the five other men who recorded videos said that they were playing as the hate-filled extremists. Hussain admitted that he agreed to appear in an al-Qaeda-style militant video, but said he was shocked when he learned of the publicity bomb plot. The jury is expected to retire next week.
