“A crime has been committed against Ukraine and we demand just punishment,” said Zelensky, the sole leader allowed to deliver an address via video to the annual summit.

Wearing his trademark military green T-shirt, Zelensky said in a pre-recorded address that Russia had violated the principles of the world body.

Zelensky called for the establishment of a special tribunal against Russia “for the crime of aggression against our state” and to ensure accountability.

He called for a fund to compensate Ukrainians for damage suffered during the invasion.

Zelensky also urged the United Nations to strip Russia of its veto power on the Security Council.

Ukraine has previously argued that Moscow holds a seat that belonged to the former Soviet Union, not Russia.
