More than 20 shots were fired at the camp, in the southern city of Curitiba, at around 4 a.m.
Brazil’s Agência Estado news service reported that police and a forensic team had attended the scene of the sghooting incident, and found shell casings from a 9mm pistol, a weapon only used by police and armed forces. The authorities are investigating.
The supporters’ camp, visited by hundreds of activists including allied politicians, leftwing intellectuals and the Argentinian Nobel peace prize winner, Adolfo Pérez Esquível, was set up when Lula was jailed earlier this month on corruption charges.
The once wildly popular former president says the charges are to keep him from running in Brazil’s October elections for which he leads the polls by a comfortable margin.
