An Argentine prison uprising over Mother's Day visiting hours killed at least 17 people before being brought under control on Sunday, according to officials and media reports.
About 200 inmates joined the uprising that began on Saturday night at the prison in Magdalena, 75 miles (120 km) south of the capital of Buenos Aires, said Argentine television station TN.
At least 17 people died before order was restored on Sunday morning, Fernando Diaz, director of the Buenos Aires province penitentiary service, told TN.
"We have taken control of the jail, which was in the hands of inmates overnight, and there is no area outside our control now," he said. "The inmates have returned to their cells and we are doing a recount."
