The Chinese Navy has seized a submersible drone from a U.S. research vessel in the disputed waters of the South China Sea, according to a report from CNN.
The report cites an unnamed U.S. defense official who said the vessel was operating two drones that were collecting data about water conditions when the Chinese Naval vessel approached and plucked one of the devices out of the water. The event occurred about 100 miles off the coast of the Philippines. It wasn't clear exactly when it happened.
The Pentagon has not officially commented on the incident, according to CNN.
