In Brazil, more than 50 people, including dozens of police officers, have died after one of the country’s largest gangs launched a series of attacks targeting police stations, military facilities and prison outposts. The uprising began on Thursday after the Brazilian government announced the transfer of several imprisoned gang leaders. Rebellions were also reported in 40 prisons. Police said prisoners were holding about 230 prison guards hostage.

• Brazilian President Luiz Inacio Lula Da Silva: “If we want to end this violence with the criminals and these organisations, we need to invest in education–that is the best weapon to create fewer gangs and more doctors.”
