Mexican Police Massacre

The 21-year-old Texan who killed 22 people in an El Paso Walmart told police following his arrest that he was targeting "Mexicans," according to an arrest warrant published Friday by US media.

Mexican prosecutors and the federal police's internal affairs are investigating allegations that officers gunned down 16 unarmed civilians in January, officials said Monday.

Mexicans furious at the presumed massacre of 43 students torched the ruling party's Guerrero state headquarters and briefly took a police commander prisoner on Tuesday as growing protests rocked President Enrique Pena Nieto's government.
