US demands China return stolen underwater drone
In the latest US-Chinese clash in the South China Sea, Washington formally requested that China return an unmanned underwater drone that its navy seized in international waters Thursday. The incident took place just as the USNS Bowditch, an oceanographic survey ship, was about to retrieve it. The device, dubbed an "ocean glider", was used to test water salinity and temperature, as part of an unclassified program to map underwater channels, Pentagon spokesman Capt Jeff Davis told reporters.
