A British court has set a September trial date for five men accused of planning to detonate bombs on London's transport system.

The defendants appeared before London's Old Bailey court Thursday via videolink from a high-security prison.

No one was hurt in the July 21 attacks when four of the men, ranging in ages from 23 to 27, tried to detonate bombs at three subway stations and a bus on July 21.  A fifth man was arrested after explosives were discovered in his backpack in London.

The charges against the men include attempted murder, possession of explosives and conspiracy to murder.

The bomb attempts came two weeks after suicide bombers killed 52 people in the London subway system and a bus.
