Whooping cough outbreaks rise: All you need to know

Floods gripped cities and towns across Russia and Kazakhstan on Wednesday after Europe's third-longest river burst its banks, forcing over 110,000 people to evacuate and swamping parts of the Russian city of Orenburg.

The worst hit areas in Russia are just to the south of the Ural Mountains, about 1,200 km (750 miles) east of Moscow. Emergencies have been declared in the Orenburg and Kurgan regions of the Urals and in the Tyumen region of Siberia.

In Kazakhstan, the worst hit areas are Atyrau, Aktobe, Akmola, Kostanai, Eastern Kazakhstan, Northern Kazakhstan and Pavlodar regions, most of which border Russia and are crossed by rivers originating in Russia or flowing from Kazakhstan to Russia.
