President Volodymyr Zelensky said Ukraine would continue to fight for its freedom in an address to the nation on its Independence Day, BBC reported.

"We need a just peace, a peace where our future will be decided only by us," he said, adding that Ukraine would fight back against Russia "while its calls for peace are not heard".

He continued: "Ukraine has not yet won, but it has certainly not lost."

Zelensky's remarks came after Moscow said Ukraine had attacked Russian power and energy facilities overnight, blaming drone attacks for a fire at a nuclear power plant in its western Kursk region, according to Reuters.
