The FDNY says the cause of a four-alarm fire that engulfed a Flushing shopping center Wednesday afternoon was accidental.

The flames broke out at a three-story, mixed-use commercial building at 135-45 Roosevelt Avenue at around 2 p.m.

Within an hour, the fire department had dispatched 33 units and 138 fire personnel.

It was declared under control around 6:15 p.m.

No injuries were reported.

Service on the 7 train  was suspended between the Willets Point and Flushing-Main St. stations in both directions for hours. It was restored just after 10:30 p.m. Wednesday.

NYC Transit says the tracks of the 7 train flooded from the FDNY's fighting of the fire.

The FDNY says it appears the fire began on a stove inside one of the businesses.
