Discontent spread to the city of Orsk, where residents staged a rare protest on Monday demanding compensation after the local dam collapsed causing the flooding.
Russia’s state-backed news agency Tass said nearly 10,000 homes, including 7,000 in Orsk alone were flooded as of Monday and water levels continue to rise.
Moscow declared a federal emergency across all flood-hit areas on Sunday and said preparations are underway for a new wave of floods in three other regions.
According to local authorities in Orsk, four people had died but they did not confirm whether the deaths had been a result of the flooding.
They also confirmed a criminal probe has been launch to assess whether possible construction violations could have caused the dam to collapse.
