Mexico government announces security plan involving military in violence-plagued border state

Mexico's top security official says military commanders will lead a new security plan for the border state of Tamaulipas, where dozens of people have been killed in drug-related violence this year.

Interior Secretary Osorio Chong said Tuesday that the state will be divided into four regions, each with an army or navy officer in charge of implementing the federal government's security plan.

Chong says federal forces will also man five new checkpoints on highways connecting the capital city of Ciudad Victoria to the cities of Reynosa and Tampico and will patrol 24 hours in urban areas.

Fighting between the Gulf and Zetas cartels has made Tamaulipas one of Mexico's most violent states. Bloodshed has risen in recent weeks after calming somewhat since 2012.
