Three defendants in the 21 July terror trial have been found guilty of a plot to bomb London's transport network, BBC reported.
Muktar Said Ibrahim, 29, Yassin Omar, 26, and Ramzi Mohammed, 25, were found guilty of conspiracy to murder.
The verdicts of three other defendants are still being considered.
At the beginning of January a court ruled that the six men planned "murderous suicide bombings" on public transport in London on 21 July 2005, two weeks after the 7 July bombings killed 52.
Muktar Ibrahim, Manfo Asiedu, Hussein Osman, Yassin Omar, Ramzi Mohammed and Adel Yahya - all originally from Africa - denied conspiracy to murder.
