IRS staff evacuate HQ after fire breaks out

Fire broke out at the headquarters of the Internal Revenue Service late Monday afternoon, forcing staff to evacuate the building.

A fire department official said the conflagration started in a transformer fire in the basement, but did not say whether any one was injured.

First responders blocked portions of streets surrounding 1111 Constitution Ave. NW in Washington, D.C., including the eastbound side of the road.

Twitter users, IRS employees and others from nearby buildings, reported smoke inside the building and outside as well.
