Again?

There might, or might not, have been another attempted bombing. For details see Europhobia. But if you want mindless speculation ... from the very scant details scraped together by Europhobia

A London Fire Brigade spokesman said: "There was a small fire on a bus and it seems there was a bag found as well. Nobody was injured."

So perhaps another attempt that went wrong like on 21/7? Or maybe explosives that where being transported but became unstable and ignited? Or perhaps nothing. In the words of Mr Nosemonkey

Don't forget we're dealing with fuckwits...
