Brazilian prosecutors are filing charges against ex-President Luiz Inacio Lula da Silva in a money laundering probe, officials say. The charges, which are related to a major corruption scandal at state oil company Petrobras, still have to be formally accepted by a judge. Lula denies any wrongdoing and says the accusations are politically motivated. He is among 16 people who are formally being accused of money laundering by Sao Paulo prosecutors.
