The helicopter crashed just south of the River Thames  near the Underground and mainline train station at Vauxhall, and the British spy agency MI6.

Video on Sky News showed wreckage burning in a street, and a large plume of black smoke rose in the area. The video from the crash scene showed a line of flaming fuel and debris.
