Hundreds of people in Dubai were evacuated from one of the world's tallest residential buildings on Saturday when fire swept through The Torch, a 79-story skyscraper, residents said.
Dubai's police chief, General Khamis Mattar, said the fire appeared to be the result of an accident and did not suspect it was caused by any deliberate criminal act, in comments carried by state news agency WAM.
He added that an investigation had started to determine the cause of the blaze, WAM reported.
A witness said flames shot out from two sides of the building as glass and metal rained down from near the summit of the structure, which stands more than 330 metres (1,082 feet) tall.
Mattar said four people had suffered minor injuries. At least a dozen fire trucks extinguished the blaze several hours after the fire alarm went off around 2 a.m. (2200 GMT Friday).
