Small explosion at News Corp. NY building

NEW YORK (Reuters) - A small chemical explosion at News Corp headquarters in midtown Manhattan on Monday injured one person, a New York Fire Department spokesman said.

Hundreds of employees were evacuated from floors 42 to 45 -- the top levels of the building -- during the incident, he said, adding that the person hurt received minor injuries.

He said the explosion happened in a 45th floor equipment room, housing heating and cooling systems for the Sixth Avenue building, and appeared to be accidental.
