The US Department of Defense is significantly expanding a militarised zone along the southern border in Texas, granting troops the authority to detain individuals for potential federal prosecution on charges of trespassing within a national defence area.
The Air Force announced on Monday the annexation of a winding 250-mile (400-kilometre) stretch of the border. This expansion comes amid a broader buildup of military forces initiated under President Trump's declaration of a national emergency at the border.
