In Brazil, at least 33 inmates were killed by their rivals in a new unrest in a prison in northern Roraima state on Friday.<br/><br/>A local government spokeswoman told AFP that latest violence at Agricola de Monte Cristo Penitentiary did not appear to be an all-out riot but rather a rapid early morning attack by one group of inmates against another, lasting less than an hour. Most of the killings were carried out with knives, as no firearms have been found inside the prison so far.<br/><br/>It is the latest eruption of violence inside Brazil's overcrowded and underfunded jails. Earlier in a grisly riot in Manaus, the capital of Amazonas state, jailed gang members beheaded and mutilated 56 of their rivals in a 17-hour bloodbath on Sunday and Monday.<br/><br/>The latest unrest comes a day after President Michel Temer said the federal government would spend USD 250 million to build at least one new prison in each of Brazil's 26 states.<br/>
