There are reports of violence in Mexico as 12 states vote for new governors.

In Veracruz, a two-party alliance backing an opposition candidate is complaining of attacks against party members in seven municipalities.

They include vehicles being burned and gasoline bombs thrown at party headquarters in the state capital of Xalapa.

The National Action Party's state leader Jose Mancha Alarcon said Sunday that attackers also burst into the home of the mayor of Acajete and set it on fire.

In the town of Emiliano Zapata near Xalapa, a severed human head was left in a park a few feet (meters) from a polling station.

State Public Security Secretary Arturo Bermudez confirmed that the driver for a local lawmaker was kidnapped. The lawmaker is part of the opposition alliance's gubernatorial campaign.
