A jury has found four men guilty of plotting to carry out a series of suicide bombings on London's transport system, a fortnight after the 7 July attacks two years ago in which more than 50 people died.
The jury has not yet reached verdicts on two other men also on trial in connection with the same plot.
Muktar Said Ibrahim, aged 29, Yassin Omar, aged 26, Ramzi Mohammed, aged 25 and 28-year-old Hussain Osman were found guilty of plotting to blow up tube trains and a bus on 21 July 2005.
Their rucksack bombs were made of hydrogen peroxide and chapati flour, and covered in shrapnel.
They claimed during a five-month trial at Woolwich Crown Court in London that the bombs were fake and were never meant to go off and were just a demonstration against the war in Iraq but the jury rejected that defence unanimously.
The jury had spent more than six days considering the verdicts and have yet to return verdicts on two other men who are also accused of taking part in the plot.
The attempts came exactly two weeks after the 7 July bombings in 2005 in which 52 people were killed by suicide bombers.
The court heard that the plan only failed because of last minute problems with the homemade explosives.
