A fire at an Indonesian retirement home killed 16 older people on Sunday evening, police said. The fire in the single-story house in Manado, Indonesia’s North Sulawesi Province, started while the residents were asleep.

“The team on the ground has confirmed that the death toll currently is 16,” North Sulawesi police spokesperson Alamsyah Hasibuan said. “Fifteen of them were burned to death, while one victim’s body remains intact.” There were 15 survivors who were treated at two hospitals in Manado, Hasibuan said.
