The 13 deaths were as a result of ingesting drugs, the ministry statement said.

The inmates, all housed at the David Viloria penitentiary center in Lara State, had started their hunger strike on Monday morning to demand the dismissal of an officer of the ministry, who they believed had been appointed director of the center.
