UNION CITY — Firefighters on Saturday night battled a set of brush fires in the hills east of Union City.

Authorities released little information about the fires after The Alameda County Fire Department tweeted around 7 p.m. that they were happening. It’s unclear how big the fires are or if they threaten any structures.
