A Ukrainian parliamentarian says Iranian-made drones’ destruction of her country’s power plants and other infrastructures by Russia to deprive the people from electricity is an act of terrorism.

“Every week we see Iranian drones over our heads destroying our buildings and civil infrastructure like electricity stations, leaving millions of people without power. It's terrorism and genocide of civilians," Yulia Klymenko, a senior Ukrainian MP told Iran International Tuesday.

The United Nations is investigating the origins of the downed drones in Ukraine. Earlier this month, Reuters quoted Secretary General Antonio Guterres as saying that any findings would be reported to the Security Council “as appropriate, in due course.”

Kyiv has accused Tehran of supplying 1700 Shahed-136 loitering munitions to Moscow, which it says have been used to hit targets in Ukraine since September. Iran denies the allegations.

Klymenko said the loss of electricity and heating caused by the drone attacks is affecting millions including women and children. President Volodymyr Zelensky said Tuesday that nearly nine million Ukrainians are left without electricity as of December 26.

Expressing disappointment over Tehran's support for Moscow inthe war against Ukraine, Klymenko stressed that PresidentVolodymyr Zelensky has clearly condemned Iran's involvement in the Ukraine war.

A top Ukrainian official, presidential aide Mykhailo Podolyak, on Saturday called for the “liquidation” of Iranian factories making drones and missiles, as well as the arrest of their suppliers. Such remarks have “political and legal consequences,” the Iranian foreign ministry spokesman, Nasser Kanani, said Monday in response without further elaboration.
