A running series of gunbattles caused at least 11 deaths in the northern Mexico border state of Tamauilpas, authorities said Monday.
Officials said the shootouts in the border city of Reynosa and the nearby town of Rio Bravo started late Sunday. Gunmen hijacked vehicles and used them to block streets, and spread bent nails to puncture tires to facilitate their getaways. Authorities called in a helicopter to support ground patrols moving to break up the roadblocks.
One group of four gunmen was killed near a gas station after they opened fire on a military patrol, officials said. Three other bodies were discovered at other points around Rio Bravo.
