HARBIN, April 13 (Xinhua) -- Twenty-two shells and two mines left by Japanese troops during World War II were found Sunday at a scrap heap in Qiqihar City of northeast China's Heilongjiang Province, local police said Tuesday.
The shells and mines, found on Sunday morning, were now stored safely in a special warehouse, said a spokesperson with the municipal police.
The police properly handled and transported the explosives. The shells and mines were very unstable after decades of corrosion and could have caused deadly explosions, he said.
Two Japanese chemical weapon units used to be stationed in Qiqihar. After the Japanese retreated, large amounts of bombs, shells and mines were left behind. Undiscovered explosives still pose a threat to local residents.
