Comments aired ahead of Putin's three-day ceasefire, as Ukraine's Zelenskyy said, "don't believe" that Russia will stick to its commitment.
Russian President Vladimir Putin said that so far, Ukraine has no need to use nuclear weapons, expressing "hope" that they are not needed.
Putin said his country has enough "power and means" to bring about the Three Years' War, triggered by Russia's 2022 invasion of Ukraine, and came to a "logical conclusion with the Russian achievements." His comments are part of a documentary that marks part of his power in power on the national television channel Rossiya 1 released on Sunday.
Putin answered questions from journalist Pavel Zarubin about Russia’s response to the Ukrainian strike, Putin said: “There is no need to use these (nuclear) weapons…I hope they won’t be asked.”
His comments, ahead of the unilateral three-day ceasefire from May 8 to 10 to mark the 80th anniversary of the Soviet Union and its victory over Nazi Germany in World War II, claimed that the initiative would test Kiev's long-term peace.
Moscow earlier rejected an unconditional 30-day ceasefire proposed by Kyiv and Washington in March.
Ukrainian President Volodymyr Zelenskyy said during a visit to the Czech Republic that he "does not believe" that Russia will abide by its truce. "This is not the first challenge, and these challenges are not the first promises made by Russia," he said.
"Today and all these days, they're talking about wanting some sort of partial ceasefire, but you should know that today's attacks are the highest in recent months," Zelenskyy said.
"So there is no confidence in them," he said, calling on Kiev's allies to increase pressure on Russia in a joint press conference with Czech President Petr Pavel.
Former NATO general Pavel said Putin could end the war with a "single decision" but he showed no "willing" to do so.
Hostiles persist as the two countries remain in conflict in a competitive ceasefire proposal.
The Ukrainian Air Force said Russia fired two ballistic missiles, with a total of 165 explosive drones and baits. 69 of them were intercepted, and the other 80 were lost, possibly blocked by electronics.

Ukrainian Emergency Services Ministry said Russia's drone injured 11 people overnight in Kyiv, the Ukrainian capital.
The Russian Defense Ministry said air defense measures shot down 13 Ukrainian drones overnight.
