Five men were wounded in several shootings in Brooklyn early today, authorities said.

A gunman opened fire in Bedford-Stuyvesant on Marcus Garvey Boulevard and Monroe Place near the Associated Supermarket about 1:35 a.m., striking three people, cops said.

A 36-year-old was shot in one leg, and grazed in the other, police said. A 23-year-old was hit in the right calf, while another victim, 20, was wounded in the hand and upper thigh.

EMS rushed them to Kings County Hospital, where they were listed in stable condition.

Eugene Belt, 62, said he had just finished watching basketball when he heard four loud shots.

“It was quiet, so you could hear them real loud. They were bang, bang, one after the other,” he said. “It sounded like they were coming from an automatic, like cannons. When the weather starts getting warm, that is when things start happening.”

He added that police recovered two guns from the scene.

There was blood on the sidewalk on Marcus Garvey Boulevard between Monroe and Madison Street.

In Crown Heights, one man was shot in the butt and thigh about 3:05 a.m. on St. John’s Place and Franklin Avenue and also taken for treatment at Kings County Hospital.

The suspect was described as having braided hair and wearing a white t-shirt and blue jeans, cops said.

Another shooter opened fire in Bedford-Stuyvesant ten minutes later, wounding the victim, 51, in the right leg on Stockton Street near Lewis Avenue.

He was listed in stable condition at Elmhurst Hospital.

No arrests have been made, and it was not immediately clear what sparked the violence.
