Two men were gunned down in Brooklyn on Monday night, police said.

The victims, ages 24 and 26, were found shot to the chest outside an apartment complex at 700 Herkimer St. in Bedford-Stuyvesant at about 9:30 p.m., authorities said.

The men were taken to Interfaith Medical Center, where they were declared dead.

One gun and four shell casings were found at the shooting scene, police sources said.

A witness said he saw people dispersing after shots were fired.

“I was upstairs listening to music and I heard the shots,” the man said. “I came out and saw people running.”

Police did not immediately provide any suspect descriptions or a potential motive for the double murder.
