Accusations that a soccer player was using witchcraft during a match in eastern Congo sparked a riot that killed 13 people, a U.N.-funded radio station reported Monday.

Most of the victims were between ages 11 and 16, Radio Okapi said. They were suffocated as panicked crowds ran for the exits during the mayhem Sunday in Butembo in eastern Congo's North Kivu province.

Radio Okapi said police tried to control the violence at Matokeo stadium in Kinshasa by firing into the air to protect their commander, who was hit in the head and wounded by fans.

The two local clubs involved were Socozaki and Nyuki System, the radio said.

Regional governor Julien Mpaluku said the government was investigating.
