[BBC] A former communist militant who Brazil's new president had vowed to extradite has been detained in Bolivia, a Brazilian official said.Italian Cesare Battisti is wanted for four murders in Italy during the 1970s, which he denies committing. Battisti spent years in Brazil as a refugee, backed by former left-wing President Luiz Inacio Lula da Silva.
But far-right President Jair Bolsonaro, who took office on 1 January, had pledged to send him back to Italy.
Filipe G. Martins, a senior aide on international affairs to President Bolsonaro, tweeted that Battisti "will be soon brought to Brazil, from where he will probably be sent to Italy to serve a life sentence".
An arrest warrant had been issued for Battisti in December, when Brazil's former President Michel Temer revoked his status as a permanent resident. The 64-year-old went on the run, and both his lawyer and the police told the BBC they had no idea of his whereabouts.
