Mr. Uribe, a presidential hopeful, was shot in June at a campaign rally in Bogotá in an attack that shocked the nation.

Political violence has become rarer in recent years, with the government and the Revolutionary Armed Forces of Colombia reaching a peace deal in 2016.

Colombian presidential candidate Miguel Uribe has died two months after being shot at a campaign event, his wife announced early Monday morning. Authorities have arrested six suspects linked to the attack.
