The death toll from a tower block fire in West London is expected to increase as rescue workers continue to tackle the blaze a day after it started.

At least 12 people died and more than 70 were injured after a fire broke out inside Grenfell Tower just after midnight on Wednesday. The number of dead is expected to jump, according to the city’s mayor.

Witnesses say children were being dropped out of windows as the flames took over the building, and authorities fear many residents are still trapped.

But many of the building's residents say they had been warning of a fire risk for months.
