Brazilian Defense Minister Fernando Azevedo e Silva announced his resignation Monday, in the latest shake-up for far-right President Jair Bolsonaro's administration, fresh off the exit of the foreign and health ministers. "I leave with this certainty: mission accomplished," Azevedo e Silva said in a brief statement, hours after Foreign Minister Ernesto Araujo submitted his resignation amid controversy over the government's problems securing more Covid-19 vaccines. bur-jhb/bgs
