Thousands of tonnes of WWII munitions corroding in the Baltic

The Baltic Sea bed is littered with mines, bombs and chemical weapons left over from the Second World War that could cause an environmental disaster as they corrode over time, a leading Polish newspaper has reported. Gazeta Wyborcza wrote on Tuesday that between 40,000 to 100,000 tonnes of war-era weaponry lie at the bottom of various parts of the Baltic Sea.
