Almost 100,000 people have been evacuated due to floods in Kazakhstan, the country's emergencies ministry said on Friday.

A state of emergency remained in effect in eight out of Kazakhstan's 17 provinces, the ministry said.

The Russian city of Orenburg battled rising water levels on Thursday after major rivers across Russia and Kazakhstan burst their banks in the worst flooding seen in the areas in nearly a century.

The deluge of melt water has forced over 110,000 people from their homes in Russia's Ural Mountains, Siberia and Kazakhstan as major rivers such as the Ural, which flows through Kazakhstan into the Caspian, overwhelmed embankments.

Residents in the city of Orenburg said the waters of the Ural rose swiftly and to far beyond breaking point, forcing them to flee with just their children, pets and a few belongings.

"It came very quickly at night," Taisiya, 71, told Reuters in Orenburg, a city of 550,000 about 1,200 km (750 miles) east of Moscow. "By the time I got ready, I couldn't get out."

Whole areas of the city were underwater, and the Ural rose swiftly to 10.82 metres (35 foot 6 inches), far above the level considered by local authorities as safe. Officials said the peak should be reached in Orenburg on Thursday.

The flooding has struck Russia's Urals and northern Kazakhstan worst, though waters are also rising in southern parts of Western Siberia, the largest hydrocarbon basin in the world, and in some places near the Volga, Europe's biggest river.

Water levels were also rising in Siberia's Tomsk, which sits on the Tom river, a tributary of the Ob, and in Kurgan, which straddles the Tobol river.

More than 6,000 people were evacuated in the Kurgan region. The flooding of the Tobol and Ishim rivers in Russia's Tyumen region will peak by April 23-25. The Tobol and the Ishim are tributaries of the Irtysh, which along with its parent, the Ob, forms the world's seventh largest river.

After the Ural burst through dam embankments in Orsk, upstream from Orenburg, on Friday, some residents expressed anger over how local officials had handled the situation, demanding greater compensation and begging for help from President Vladimir Putin.

The Kremlin said Putin would hold a meeting with Emergencies Minister Alexander Kurenkov and the governors of Orenburg, Kurgan and Tyumen, the worst affected regions. The Kremlin said Putin was devoting a significant part of his day to the floods.

In Orenburg, some residents expressed disappointment that local officials had not done enough to prepare for the annual snow melt.

"There is a lot of excitement, indignation and strong emotions that I understand and share," Orenburg Mayor Sergei Salmin said. "The issue of receiving compensation and the procedure for processing payments is one of the main ones."
