Twelve people have died in a west London tower block fire and the number of deaths are expected to rise, police have said.

Mark Fishlock was a firefighter for more than 30 years. He explained to Radio 4's PM the difficulty of tackling such a fire.

"It spread externally and there is no simple way for firefighters to put water on fires outside very tall buildings," he said.

"It is almost an unsolvable problem."
