Three people were struck by gunfire during a shooting in Queens on Sunday night, cops said.

The victims — one of which was shot in the back — suffered non-life-threatening injuries when they were struck by bullets at around 8:15 p.m. outside a home at 188-42 Mangin Avenue in Jamaica, according to police.

“I was in the house and it sounded like firecrackers,” a 41-year-old neighbor who identified herself as Sharon told The Post.

“It didn’t sound like nothing, just like ‘pop,pop,pop.’ I’m like ‘bunch of idiots!’ ”

A source said that the motive for the shooting was likely gang-related.

All three victims were transported to a local hospital, where they were expected to survive.
