A prison riot in southern Mexico’s Tabasco state left seven inmates dead as family members tried to break into the prison to check on their relatives.
Four police officers and six other inmates were injured in the incident that took place in the town of Villahermosa on Thursday.
The BBC’s Latin America correspondent Will Grant examines what happened when Mexico’s president announced an investigation into the riots.
