Occurring just hours apart this weekend, the two shootings have left at least 29 people dead and over 50 injured.

 

Six Mexicans were among the people killed in the shooting spree, while another seven Mexicans were among the injured.

 

The shootings occurred in El Paso, in the U.S. state of Texas, and in Dayton, in the state of Ohio. Authorities are treating the El Paso incident as an act of domestic terrorism, according to U.S. media.
