The four bombers died in the blasts, but Waheed Ali, Sadeer Saleem and Mohammed Shakil were accused of helping them by conducting reconnaissance and conspiring with them.

Two of the men — Ali and Shakil — were convicted of a second charge of conspiracy to attend a place used for terrorist training.

Tuesday’s verdicts came at the end of the men’s retrial at Kingston Crown Court in southwest London. A separate jury failed to reach a verdict in their first trial, which ended in August after three months.

The bombings in 2005 killed 52 people in blasts on three subway trains and a bus. At least 900 people were wounded.

It was evidence found at the bomb sites that first led police to Ali, Saleem and Shakil.

Investigators found the mobile phones of two of the suicide bombers, Mohammad Siddique Khan and Germaine Lindsay. Khan’s phone had numbers for Saleem and Shakil, and Lindsay’s phone had a number for Ali.

Police arrested the three in March 2007 after piecing together what they called a “complicated jigsaw with thousands of pieces.” They were charged in April 2007.

The discovery of the mobile phones allowed investigators to start tracing the call records and determining how closely the men were connected.
