The leading candidate in next month's presidential election in Brazil has been stabbed at a campaign rally and is reportedly in serious but stable condition following surgery.
Jair Bolsonaro, a former army captain whose far-right views have placed him ahead in the polls, was being carried on the shoulders of supporters in the southeastern state of Minas Gerais when he was attacked by someone in the crowd.
Supporters of Bolsonaro then descended on the assailant, beating him before police were able to take the man into custody.
Video of the incident shows Bolsonaro giving a thumbs-up just before being stabbed. The candidate appears to grimace, then double over in pain. He is then lowered and quickly bundled into a car.
Police say they have arrested a 40-year-old man identified as Adelio Obispo de Oliveria in connection with the stabbing. Reuters quotes officials as saying the suspect is mentally disturbed.
According to reports, doctors say it could take Bolsonaro up to two months to fully recover and that he would be in the hospital for at least a week — throwing the rest of the campaign into question.
"His internal wounds were grave and put the patient's life at risk," said Dr. Luiz Henrique Borsato, who operated on the candidate, according to Reuters.
The doctor said the biggest challenge for medical staff would be preventing an abdominal infection.
Bolsonaro has sparked outrage among many in Brazil for his racist and homophobic comments on the campaign trail. Even so, he has remained strong in the polls.
His would-be closest rival, former President Luiz Inácio Lula da Silva, has been disqualified from the race after being convicted of corruption. Bolsonaro is well ahead of other presidential hopefuls in the opinion polls. They include former Senator Marina Silva and Gerald Alckmin, a former governor of São Paulo.
As Reuters notes, "The attack on Bolsonaro, 63, is a dramatic twist in what was already Brazil's most unpredictable election since the country's return to democracy three decades ago. Corruption investigations have jailed scores of powerful businessmen and politicians in recent years, and alienated infuriated voters."
