San Jose firefighters battled a three-alarm fire at an abandoned youth center early Friday morning, containing the fire to the building where it started.

The San Jose Fire Department said that at 1:08 a.m., crews responded to the fire at the MACSA youth center in the 600 block of Sinclair Drive.

Images posted by the department on social media showed a significant fire engulfing portions of the multi-story building, with thick smoke plumes rising from the structure.

No injuries were reported. Fire officials said it was challenging to fully knock down the fire because of the many enclosed compartments within the structure.

The department said crews will remain on scene throughout the day for fire watch. The cause of the fire is still under investigation.
