Ukrainian forces are closing in on Kherson, while Russian forces are building up defences inside it.
Both sides see the city, in the south of the country, as important to control. However, military experts say a battle for it could prove very costly.
Before the war, Kherson had a population of about 380,000.
It is on the banks of the Dnipro river, near the Black Sea coast.
It is also close to the Crimean peninsula – a part of Ukraine which Russia annexed in 2014 and which contains a number of its military bases.
