PARKCHESTER - The Office of Mayor Michael Bloomberg is denying that firefighters were delayed in responding to a massive fire in Parkchester.

The five-alarm blaze broke out on Commonwealth Avenue and quickly spread to a neighboring building. The Uniformed Firefighters Association alleges it took more than eight minutes for firefighters to receive word of the fire, yet the deputy mayor of the FDNY and other city officials say those claims are inaccurate.

Five families were displaced after the raging fire engulfed two multi-family homes.

The president of the Uniformed Firefighters Association says the delay may have caused the fire to rage out of control. The union also plans to bring the city's emergency response system in front of a judge.
