Cops are searching for three teens who were throwing rocks at school buses shuttling kids from a Jewish all-girls school in Brooklyn, authorities said Thursday.

The three punks were caught on surveillance video just after 4 p.m. Tuesday, hiding behind an SUV and throwing rocks at the passing buses — then laughing as they ran away, video released by police shows.

The buses, one of which had a window shattered after being hit by a rock, were taking kids home from Associated Beth Rivka School in Crown Heights, cops said.

There were no injuries, and the NYPD’s Hate Crime Task Force is investigating the incident, police said.
