HONOLULU (AP) - Residents say they didn't realize a deadly inferno was raging in their high-rise apartment building in Honolulu until they opened their doors and saw firefighters racing to battle the flames.

Several Marco Polo high-rise residents told The Associated Press the sirens are located in the hallways and they had trouble hearing them when the blaze started. They also said there were no flashing alarm lights or public announcements about the deadly fire Friday.

Three people died.

Fire officials have not released any information about a possible cause for the blaze.

A fire official has said the building didn't have fire sprinklers, which officials say would have stopped the flames from spreading.

The building was built in 1971, before sprinklers were mandatory in high-rises.
