A gubernatorial candidate in the state of Tamaulipas, Mexico, was killed by gunfire Monday morning in Ciudad Victoria, the government-run Notimex news agency reported.
The candidate, identified as Rodolfo Torre Cantu, belonged to the Institutional Revolutionary Party, known by its Spanish acronym PRI.
Three other people, including his campaign manager, also were killed in the shooting, Notimex said. Another four were wounded and transported to the Doctor Norberto Trevino General Hospital in Tamaulipas, where they were under heavy guard, the news agency said.
Mexico holds elections Sunday and Torre was considered a front-runner in his race.
