Troops in Brazil have been deployed to the north-eastern state of Ceara, after a rise in violent crime there.

Over the past week, the state has seen a wave of attacks including a bomb explosion, torched buses and assaults on banks and public buildings.

Police say it's in retaliation against President Jair Bolsonaro's crackdown on gangs.
