The cause of the wildfires that swept through part of Long Island, New York, over the weekend is believed to have been a resident making s'mores, police said.

Investigators say embers from a backyard fire spread rapidly, fueling blazes that prompted evacuations and an emergency burn ban.

Gov. Kathy Hochul issued a burn ban for Long Island, New York City and the Hudson Valley following the large wildfires.

All four Long Island brush fires that sent soaring plumes of smoke into the air had been contained by Sunday afternoon, authorities said.

Firefighters in New York have knocked down a dwindling brush fire in a wooded stretch of Long Island but officials say high wind gusts could leave the region vulnerable to additional blazes
