MEXICO CITY — A day after tens of thousands of Mexicans joined in anti-violence protests, President Felipe Calderon offered Monday to meet with organizers to explain a government drug war that has produced growing worry as deaths climb.
Also Monday, authorities in the state of Durango reported discoveries of 11 bodies in a mass grave in the state’s capital. Officials also said six human heads were dumped next to a school there.
In Tamaulipas, 12 gunmen and a Mexican marine were killed in a shootout at Falcon Lake, a dammed stretch of the Rio Grande straddling the border with Texas. The lake is where a U.S. citizen, David Hartley, was reported by his wife to have been pursued and shot by gunmen while riding a personal watercraft last year.
