"Mexico's National Guard Reinforces Ambush Site with 300 Troopers After Police Officer Massacre"

Mexico has deployed 300 National Guard troopers to the state of Guerrero following the ambush and killing of a police chief and 12 officers. The attack, one of three in the region on Monday, has prompted an investigation, with some bodies found handcuffed and face down on the ground. The escalating gang conflicts in the southwest have led to a surge in violence, with at least 341 police officers killed in Mexico this year.
