Chinese nationals have snuck onto military bases and other sensitive US sites more than 100 times in recent years — sparking federal investigations into possible spying, according to a report Monday.
Alarming cases include people crossing into a United States missile range in New Mexico — and scuba divers swimming near a rocket launch site and Kennedy Space Center in Florida, officials told the Wall Street Journal.
Some have also used drones to take detailed aerial footage of sensitive military sites — while the Pentagon confirmed cases of people “speeding through security checkpoints.”
Many would-be intruders, however, claim to be confused tourists who think they have a reservation at an on-base hotel — and they often use what appears to be scripted language when confronted by security, the report said.
