Ukrainian President Volodymyr Zelenskyy on Tuesday lamented the lack of decisive action by the UN Security Council over Russian aggression.

Addressing the Council members in New York, Zelenskyy slammed Russian President Vladimir Putin and ally China.

"Putin only cares about using every meeting, every chance to keep the war going. Each day Russia kills our people, destroys our cities and leaves no sign it will ever return to the principles of the U.N. charter, the Ukrainian leader said.

Zelenskyy earlier held a bilateral meeting with US President Donald Trump.
