Coordinated initiative of three agencies

The US Departments of Transportation, Defense and Homeland Security on Friday announced a coordinated initiative to enhance airspace security along the US-Mexico border. A temporary flight restriction (TFR) has been introduced, prohibiting unauthorized drone activity.

Parameters of the restriction

The restriction took effect on Friday. It prohibits any unauthorized drone flights at altitudes up to 400 feet (122 meters) above ground level and extends one nautical mile (1.9 km) north of the US-Mexico border.

Goals and statements by officials

According to the agencies, the measure is aimed at reducing risks to border security operations, protecting federal personnel and facilities, and countering threats that the administration links to drug cartels and other illegal activities. Transportation Secretary Sean P. Duffy said the measure continues President Donald Trump's efforts to strengthen border security and combat drone-related threats. Defense Secretary Pete Hegseth said the restrictions will give military commanders a better understanding of potential threats and more options for responding to drone activity, adding: 'The US government will maintain 100 percent operational control of our border: land, air and sea.' Homeland Security Secretary Marcwayne Mullin noted that the initiative will continue the administration's efforts to secure the border and will help protect federal personnel by countering cartel drone threats.
