Mexican military forces shot down an unregistered drone over South Korea's closed training session in Zapopan, Guadalajara, on the morning of 18 June, hours before the two nations met at Estadio Akron 1. South Korea coach Hong Myung-bo confirmed the drone had been seen over the session. "The drone was seen over the session and it was unfortunate," he said 2. The operator and intent remain unconfirmed.
The interception came under Plan Kukulkan, the federal security operation overseen by President Claudia Sheinbaum and built after the El Mencho killing to keep cartel violence away from venues. The same perimeter saw around 2,000 protesters clash with riot police at the Azteca on opening day . A drone filming a warm-up is a different threat class from an armed attack: low-cost commercial surveillance rather than narco violence.
The same counter-drone equipment answers both, which is why the interception folded into the existing footprint without a new operation. For every team training in a Mexican host city, closed-session secrecy has become a counter-drone problem rather than a purely tactical one. A plan designed against organised crime is catching opponents trying to spy on each other, a mandate widening match by match.
