London - A helicopter that crashed in London apparently "plummeted straight into the ground", said an ex-BBC producer.
The helicopter crashed near the River Thames in London.
A photo shown on Sky News showed wreckage burning in a street.
According to Scotland Yard, the helicopter apparently hit a crane on top of a building.
Large plumes of black smoke were seen rising in the area, close to the Waterloo train station during the early morning rush hour.
There were no immediate reports of casualties but Sky News said at least one person was on the helicopter.
