Former Brazilian President, Luiz Inacio Lula da Silva, reacts during a press conference on the accusations of corruption against him in Sao Paulo, Brazil, on Sept. 15, 2016. President of the Brazilian Workers' Party (PT) Rui Falcao said on Wednesday that accusations against former President Luiz Inacio Lula da Silva are "another episode of persecution" and an attempt to stop Lula from running for president in 2018. On Wednesday, investigators accused Lula, who served as president from 2003 to 2010, of leading a vast corruption ring at Brazilian oil company Petrobras. (Xinhua/Rahel Patrasso)
