Malaysia's maritime agency said Tuesday a Chinese barge likely plundered two World War II British shipwrecks in the South China Sea after discovering 100 more old artillery shells on the detained vessel. Malaysian media reported that illegal salvage operators are believed to have targeted the HMS Repulse and the HMS Prince of Wales, which were sunk in 1941 by Japanese torpedoes days after the attack on Pearl Harbor. A total of 842 sailors perished, and the shipwrecks off the coast of Malaysia's central Pahang state are designated war graves.
