Apple's Cupertino campus was the scene of a three-alarm fire Tuesday night. Firefighters spent over three hours fighting to extinguish the blaze, and finally managed to put the fire out early Wednesday morning, according to the San Jose Mercury News.

Over 60 firefighters from the Santa Clara County, San Jose, Saratoga, and Los Altos fire departments responded to the incident after Apple employees reported smoke in the area and a possible fire on top of the building.

The fire burned the roof and second level of the Valley Green Six building at Apple's California headquarters, but there were no injuries. The building, however, suffered from smoke, fire and water damage.

Santa Clara County Fire deputy chief, Hal Rooney, did not have an estimate on the damage to the building, and Apple has not commented on the incident.
