PRAHOVO, SERBIA - AUGUST 11: Sunken hulls of World War II-era Nazi warships lie exposed in the Danube River near Prahovo, Serbia on August 11, 2026. Extreme heat and severe drought across Europe have caused water levels in the river to drop to historic lows, revealing dozens of scuttled German vessels laden with explosives from 1944. According to some estimates, around 200 World War II shipwrecks lie on the sandy bed of the Danube.
