Details on London bombs of 7/7
According to the New York Police, from information they say is from the British, the bombs used household ingredients and were set off by mobile phones. I don't really understand this last bit, why if this was the case were they suicide bombers (and if it was a mobile phone in the Piccadilly line it would have had to be its timer or something, as signals don't work down there [Update: Whoops didn't read closely enough, yes, it says it was the timer set to 8:50)].Update II: It appears the New York Police should not have revealed the information. It appears the British public is not ready for it, or something like that.
