CIUDAD VICTORIA, Mexico (AP) — Mexican authorities say they have found 19 shot and burned bodies near a town across the Rio Grande from Texas in an area that has seen violent territorial disputes between organized crime groups in recent years.

GUATEMALA CITY (AP) — Relatives of migrants from Guatemala said Monday they believe that 13 of the 19 charred corpses found in a northern Mexico border state could be their loved ones and the country's Foreign Ministry said it was collecting DNA samples from a dozen relatives to see if there was a match with any of the bodies.

If true, the killings would revive memories of the 2010 massacre of 72 migrants in the same gang-ridden state of Tamaulipas.
