The Russian-installed administration of Ukraine's Kherson region said on Tuesday that it was preparing to evacuate three districts after the overnight breach of the Kakhovka dam, holding 18 cubic km of water.

In a statement on Telegram, the administration said evacuations were being prepared in the Nova Kakhovka, Golo Pristan and Oleshky districts, the latter two across the mouth of the Dnipro river from the Ukrainian-held regional capital, Kherson.
