Hong Kong police launch air-land-sea lockdown for underwater mine removal after discovery of wartime device with over 220kg of explosives

Hong Kong police have launched an air-land-sea lockdown in the southeastern part of the city in preparation for an underwater operation to destroy a wartime naval mine filled with more than 220kg (485 pounds) of high explosives.

Acting senior superintendent Suryanto Chin-chiu of the force’s explosive ordnance disposal bureau said on Thursday it was the first time a complete British-made mine had been found in the city in the past three decades.
