The Kremlin has warned that water levels have yet to peak in several regions of the country as tens of thousands in southern Russia -- and in neighboring Kazakhstan -- scrambled to avoid some of the worst flooding in decades as unseasonably warm temperatures melt snow faster than usual.
More than 10,000 homes have already been flooded by water cascading from the Ural Mountains and Siberia, with thousands more at risk, according to local officials.
In northern Kazakhstan, the situation is said to be worse, with more than 86,000 people evacuated.
Several regions in both countries have declared states of emergency as officials scramble to coordinate their response.
"Difficult days are still ahead," Kremlin spokesman Dmitry Peskov told reporters in Moscow on April 9. "There is a lot of water coming."
Peskov said Russian President Vladimir Putin held telephone talks with his Kazakh counterpart, Qasym-Zhomart Toqaev, on joint efforts to deal with the disaster.
"Close collaboration of the two nations' corresponding agencies that have been jointly monitoring and forecasting the situation, outlining and implementing coordinating measures to react to the situation were emphasized during the talks," a statement on the Kremlin website said, adding that "the leaders of the two countries agreed to intensify emergency efforts."

At least five people have died during the floods, and on April 8 local residents picketed the local government headquarters in Orsk, demanding increased official action and urging Putin to intervene.
Peskov told reporters on April 9 that Putin did not plan to visit the Orenburg region at the moment, stressing that the president "is taking care of the issue" without being at the site.
