In Brazil, a state governor is refusing to back down on his prison reforms - despite retaliation from organised criminal gangs.

Prisons built to hold captured gang members have instead become centres of power for the criminal syndicates and authorities have vowed that must not be allowed.

The gangs launched a wave of attacks in Ceara state, prompting President Bolsonaro to send in national troops and the state government to crack down on the prisons even further.
