Ukraine's president makes a rare trip outside the capital to visit bomb-damaged Mykolaiv and Odesa.
During his last trip, Mr Zelensky told Ukrainian troops on the front line, "Take care of Ukraine - the only thing we have", his office said.
In the ferocious war which has followed, the UN says that more than 4,500 civilians have been killed and nearly 5,600 have been injured. Thousands of combatants have also been killed or injured on both sides.The West has responded to the invasion by imposing severe sanctions on Moscow and supplying weapons to Ukraine but has not intervened directly in the war against Russia, a nuclear superpower.
Meanwhile, the secretary of Ukraine's National Security Council has dismissed reports from certain government officials that as many as 500 Ukrainian soldiers could be dying every day. In Kyiv, Mayor Vitali Klitschko has told the BBC his country will only enter peace talks after the "last Russian soldier has left Ukraine".
