Brazil’s far-right president Jair Bolsonaro, who was stabbed in the abdomen at a campaign rally a year ago, will undergo surgery next week, his third surgical procedure since the attack although doctors say this one carries only a minor risk.

Axar.az reports citing Reuters.

Bolsonaro, a former army captain, will spend about 10 days recuperating after the procedure, he said on Twitter. The surgery will treat a hernia that developed following his previous surgeries, said Leandro Echenique, one of the president’s doctors.

“It is common for an hernia to develop where you have had abdominal surgery,” Echenique said. “This is a surgical correction ... the president is doing very well health-wise.”

Adélio Bispo de Oliveira, the man accused by prosecutors of stabbing Bolsonaro last September, was acquitted in June after a judge decided that he was mentally unfit.
