At least one person was shot dead on Thursday during clashes with police as demonstrators sought to block Kenya's presidential re-run in the western city of Kisumu, police and hospital sources said.

"He was brought here with a gunshot wound to the upper thigh. He died in the hospital," a hospital source told AFP, explaining that he had died of massive blood loss. The police source confirmed the information and said a second protester had been killed, but AFP was unable to immediately confirm the report.
