First video from London towering inferno

A video has emerged showing the flooded ground floor of Grenfell Tower with firefighters surrounded by mangled wreckage caused by the inferno.
These first pictures inside the stricken inferno tower reveal the flooding and horror that would have been faced by residents as they scrambled for their lives.
Blackened hand prints can be seen on the stairwell walls, rivers of waters can be seen flooding through the hallways and possessions are left abandoned on the ground.
