A prison riot in the southern Mexican state of Tabasco has left seven inmates dead, prompting family members to try to break in to check on their relatives.
Four police officers and six other inmates were injured in the incident, which broke out in the town of Villahermosa on Thursday.
The BBC's Latin America correspondent Will Grant investigates what happened when Mexico's president announced an investigation into the riot.
The video was produced by Ottilie Mitchell, Ian Casey and Suneil Asar.
