Police appealed for information based on the CCTV images
Met Assistant Commissioner Andy Hayman said anyone who knew who or where the men were should contact police.
The bombers fled after detonators went off but failed to set off explosives.
The fatal police shooting of a man at Stockwell Tube station on Friday was linked to anti-terrorist operations, Met Police chief Sir Ian Blair said.
Scotland Yard urged anyone who knew where the men captured by CCTV were to call 999, or if they could identify any of them to call the anti-terrorist hotline on 0800 789 321.
Officers raided three addresses across the capital on Friday as part of anti-terrorist operations.
That included a search of an address in Harrow Road, west London, where area resident Patricia Osbourne said she heard six shots fired.
