London fire: At least six dead in high-rise blaze

Police have confirmed six people have died and 20 are in a critical condition after fire engulfed a high-rise apartment block in west London.

Nine hours after the start of the blaze police are warning the number of fatalities will rise.

Mayor Sadiq Khan is demanding answers over the safety of the building after residents raised concerns about a fire risk last year.
