Britain, France, Germany and the US have stressed the need to ensure the safety of nuclear installations threatened by the conflict in Ukraine.
In a phone call on Sunday, the four leaders also reiterated their support for Ukraine against Russia’s invasion.
Moscow and Kyiv have accused each other of shelling a Russian-held nuclear plant, raising fears of a catastrophe.
Meanwhile, President Volodymyr Zelensky urged Ukrainians to be vigilant ahead of Independence Day celebrations.
“Russia could try to do something particularly disgusting, particularly cruel,” he said in a weekend address.
“One of the key objectives of the enemy is to humiliate us,” he added, but “we have to be strong enough to resist all provocation”.
