Conspiracy 7/7: The London Bombings Four Corners : Season 49 Episode 30

The BBC's Conspiracy Files investigates a range of remarkable claims that have been made after the bomb attacks on London's transport system four years ago. Why did the government claim the bombers had travelled to London on a train that didn't run on that day? Did Israeli security forces know of the attacks in advance and then warn their officials visiting London not go near the targeted locations? These are just some of the remarkable claims being made.
