The top two floors of an office building near Scotland Yard have collapsed following an explosion. The campaign office of Labour Deputy hopeful Hazel Blears is on a lower floor of the building. Reports suggest the upper floors were undergoing renovation, and only one person has been injured.
According to the BBC:
Eyewitness Barshan Ganwari said he heard a "huge noise" or "a blast" and saw "people running away" from the scene.
Justin Linger was working in the building at the time of the collapse.
"I was just sitting in the office when all of a sudden the whole building shook," he told BBC News 24.
"As one of my colleagues put it, the building disco danced."
He said the floors affected were undergoing renovation.
