KYIV - Ukraine's President Volodymyr Zelenskiy has put forward a bill that would see Ukraine impose sanctions on Russian ally Iran for 50 years, Zelenskiy's chief of staff Andriy Yermak said on Sunday, a response to what Kyiv says is Tehran's weapons supplies to Moscow.

Kyiv and its allies say Iran has been supplying Russia with arms, including hundreds of drones, since Moscow invaded Ukraine last year. Tehran rejects the allegations.

If passed by Ukraine's parliament, the bill would stop Iranian goods transitting through Ukraine and use of its airspace, as well as imposing trade, financial and technology sanctions against Iran and its citizens.

Kyiv said on Sunday that Moscow had staged the largest drone strike to date on Ukraine overnight, using 54 Iran-made drones. It said 52 of them were shot down.
