Mexico City: At least three people were killed and seven others injured in a fire at a men's prison in Mexico City, officials said.
"We are saddened to have to report that due to a fire, three people were killed, so we are expressing our deepest condolences to their families," the Mexico City Penitentiary System Undersecretariat said in a statement on Thursday.
The fire started around 5.25 a.m. in Dormitory 2 at the Reclusorio Preventivo Varonil Oriente, officials said, adding that it took several hours to put out the blaze.
The cause of the fire has not been determined, but investigators are working on the case, prison officials said.
Mexico City Penitentiary System Undersecretary Antonio Hazael Ruiz told Milenio Television that the fire started in a kitchen and was not the result of a fight or riot.
"We have ruled out any kind of violence or riot. It was an accident, we're not sure of its origin, possibly a small frying pan, which are electric," the official said.
