Polish Prime Minister Mateusz Morawiecki confirmed that the release of an unidentified toxic substance has contaminated the Oder River, as the government offered a reward to find out who is responsible for polluting the country’s second-longest waterway.

Tons of dead fish have been hauled from different parts of the river on the border with Germany in the last two weeks, in what some environmental groups have described as Poland’s biggest disaster in years.
