US imposes temporary drone flight restrictions along southern border

The US FAA has issued a temporary flight restriction (TFR) barring unauthorized drone operations up to 400 feet AGL within 1 nautical mile north of the US-Mexico border. This is a routine security measure, likely aimed at countering cross-border drone smuggling or surveillance, but the specific trigger and duration remain unspecified. The restriction signals heightened border security posture but has limited direct market impact.
