Brazil's Bolsonaro seriously injured in knife attack Brazil's right-wing presidential frontrunner Jair Bolsonaro was seriously injured when he was attacked with a knife while campaigning in the country's southeast, his son said. Flavio Bolsonaro -- who initially described his father's wounds as superficial -- later tweeted that the 63-year-old suffered injuries to the liver, lung and intestine and had "lost a lot of blood."
