On Thursday, Mexican officials announced plans to deploy 6,000 Mexican National Guard troops to Mexico’s southern border. The deployment will consist of 13 units made up of between 450 and 600 troops. Ten units will be sent to the border with Guatemala, where most Central American asylum seekers cross into Mexico, and three will operate in the Isthmus of Tehuantepec region of southern Mexico. The troops are set to arrive by September.
