Dam break causes chaos in Russia's Orenburg region. The flood will reach the regional capital in three days, so the authorities have evacuated thousands of residents of Orsk and declared a state of emergency.
Two days later, on April 5, the infrastructure burst due to the flooding of the Ural River and left at least two dead. The first Orsk dam was built in 2014 at a cost of about 910 million rubles, more than 200 million euros at the then exchange rate.
