Brazil's far-right president, Jair Bolsonaro, appointed an army reserve officer to lead state-owned energy giant Petrobras, after criticizing several successive increases in the price of fuel. "The government decided to appoint Joaquim Silva e Luna to fulfill a new mission, as ... president of Petrobras, after closing the cycle, exceeding two years, of the current president Roberto Castello Branco," said a brief note from the Ministry of Mines and Energy, published by the president on his Facebook account. val/mel/gma/st/mdl
