Sunken German warship from WWII resurfaces due to low river levels in Serbia

Europe's prolonged summer heatwave has driven water levels in the Danube River to unusually low levels, revealing dozens of German warships that were deliberately sunk by retreating Nazi forces during the Second World War.Near the Serbian town of Prahovo, the receding river has exposed the rusting remains of vessels scuttled in the autumn of 1944 as German troops withdrew before the advancing Soviet Red Army. The ships were intentionally sunk to prevent military equipment from falling into enemy hands and to block the Danube, Europe's second-longest river, in an attempt to slow the Soviet advance.The wrecks, many of which reappear whenever drought causes the river to shrink, have become increasingly visible as persistent heat and dry weather grip much of Europe.
