Four men convicted for their role in the failed 21 July suicide bombings in the UK have lost their appeal. No further legal avenues remain for them to challenge ther convictions.

Four men serving at least 40 years for the failed 21 July suicide bombs have lost a Court of Appeal bid to challenge their convictions.

Three judges rejected applications brought by Muktar Said Ibrahim, Yassin Omar, Ramzi Mohammed and Hussain Osman for leave to appeal.

Last July, the men were jailed for life for conspiracy to murder.

They had tried to detonate rucksacks filled with explosives on three Tube trains and a bus in 2005.

The planned attacks came two weeks after 52 people were killed and more than 770 were injured when four suicide bombers blew up parts of the London transport network.
