MEMPHIS, Tenn. (AP) — Fire officials in Tennessee say nine people — four adults and five children — have died after a blaze burned a home in Memphis. Family members told reporters that 11 people perished.

Fire Department Lt. Wayne Cook said the first firefighters who arrived at the scene about 1:30 a.m. saw smoking coming out of the one-story home where a family lived. He said it took about 15 minutes for firefighters to extinguish the blaze.

Officials are trying to determine what caused the fire. Sweat said it’s the most deaths in a single fire in the city since the 1920s.
