Several children were among the dozens who were injured during a major shooting incident at a subway station in Brooklyn when a suspect fired at least 33 shots and used smoke grenades on the train, authorities said.

Juvenile victims, including a 12-year-old, were transported to Maimonides Hospital in varying conditions, following Tuesday’s violent attack that injured 29 victims, WABC reported.

The children were reported on their way to school when the attack occurred, officials said.

"It was a pretty devastating injury to the thumb and it destroyed a lot of the bone, the joint, the tendons, the nerves but we were able to salvage the thumb and it's alive and he will need some more surgery," hand surgeon Jack Choueka said, WABC reported.

Two other victims, ages 13 and 15, who suffered minor injuries have already been released from the hospital, according to the report.
