Eleven people were shot in less than 12 hours across New York City as of early Sunday morning, law-enforcement sources told The Post.

The victims were wounded during eight shootings in Brooklyn, The Bronx, Queens and Manhattan between 5:30 p.m. Saturday and about 5 a.m. Sunday, sources said.

Most were expected to survive, but a 30-year-old woman who was shot in the head was rushed to NYC Health + Hospitals/Bellevue in Manhattan, where she was in grave condition, sources said.

In at least three incidents, the victims refused to cooperate with the NYPD after being wounded, sources said.

The spree of gunfire brought the number of shootings since Monday to 59, with a total 81 people shot, including six murders.

By comparison, there were nine murders but just 26 shootings for the entire week during the same time last year, sources said.
