Three men were wounded — including one critically, shot in the head — during a drive-by shooting outside a shuttered laundromat in the Bronx Thursday, cops said.

The victims were hit outside the Commonwealth Ave. laundromat near Randall Ave. in Soundview around 3:17 p.m., according to law enforcement.

Police sources said the shooter was riding in a white SUV heading north on Commonwealth Ave. when he opened fire at a crowd outside the laundromat.

“They were just hanging out,” said a 30-year-old man who witnessed the shooting from across the street. “A white car drove by and started shooting. Everyone started diving under the cars.”

A 29-year-old man was struck in the head, another man, also 29, was hit in the left shoulder, and a third man, 28, was struck in the back, police said.

“There were five shots,” said a woman, 57, who was standing two doors down from the laundromat when the shooting started. “All three of them were down on the ground.”

“One guy was shot in the head,” she added. “He was face-up. His brains were on the floor.”

Medics rushed all three victims to Jacobi Medical Center, where the man struck in the head was listed in critical condition.

The other two victims are expected to survive.

Two cars, a grey Jeep and a silver Volkswagen, were seen with bullet holes in their rear driver’s side windows.

There were no arrests.
