A 15-year-old boy was shot in the leg on the Upper East Side Wednesday night, police said. 

The teen was blasted shortly before 6 p.m. near East 60th Street and 3rd Avenue, according to cops.

He was taken by EMS to NewYork-Presbyterian/Weill Cornell Medical Center in stable condition, the NYPD said.

It’s unclear what led to the bloodshed, and no arrests have been made. 

The shooting is part of a bloody week for youth violence, including when a 15-year-old boy was stabbed by another teen Tuesday in Brooklyn’s Edward R. Murrow High School 

Earlier Wednesday, a 12-year-old girl was slashed by a fellow student in a Bronx classroom.
