Firefighters in Waco have responded to a reported two-alarm fire at the Mars candy plant at 1001 Texas Central Parkway.

KWTX reports that fire units were dispatched around 1:10 PM Tuesday after a call about a fire in a trailer at a loading dock. The first unit to arrive requested backup and reported heavy black smoke, which is visible on KWTX's SkyCam.

A reporter on the scene said the plant was being evacuated.
