London (CNN) - A helicopter crashed into a construction crane atop a new luxury residential building in thick London fog Wednesday, killing two people and sparking a line of flame when it plunged to the ground.
Nine others were injured in the crash that took place at the height of the morning rush hour in Vauxhall, south of the River Thames in central London.
One was critical, but police said the others did not appear to be seriously hurt.
The crash did not appear to be terrorism-related, police said.
