GRAPHIC CONTENT WARNING: People jump from 20-storey building in Pakistan to escape fire

At least four people were killed and several injured as they tried to escape a fire in an office building in Lahore, Pakistan. The fire started at around noon on the 7th and 8th floors of the building and rapidly engulfed three more floors, trapping several people inside. Horrified onlookers watched from the street below as those in the building waved for help from the smoke-filled rooms. Two men were filmed jumping from the building rather than face the flames. One died on impact and the other later in hospital. Report by Matt Blake.
