Ukrainian President Volodymyr Zelenskyy told a conference on Ukraine reconstruction on Tuesday that Russian rockets and Iran-made drones had destroyed more than a third of his country's energy sector.

Zelenskyy also told the conference in Berlin via video link that Ukraine had yet to receive "a single cent" towards a fast recovery plan worth a total of $17 billion.

There's no immediate response to Zelenskyy's remarks from Russia and Iran.
