During a security operation targeting the Gulf Cartel in Matamoros, Mexican police gunfire from a helicopter killed a 7-year-old girl named Aranza, who held dual U.S. and Mexican citizenship.
The operation resulted in the arrest of Axel Alfredo Cárdenas Rodríguez, the son of an alleged cartel leader. In total, six people died during the operation and subsequent cartel-led roadblocks.
