Ecuadorian presidential candidate Fernando Villavicencio, a vocal critic of corruption and organized crime, was killed on Wednesday evening during a campaign event in northern Quito, authorities said.

Local media reported Villavicencio had been shot, but Ecuador's police and Interior Ministry did not respond to repeated requests for comment about the details of the killing.

The attorney general's office said a suspect in the crime later died of injuries sustained in a shoot-out. The violence injured nine other people, including a candidate for the legislature and two police officers.
