Volodymyr Zelenskyy has welcomed the news that the US will send an additional $2.3bn (£1.8bn) in security assistance to Ukraine.
US defence secretary Lloyd Austin said yesterday that Washington would soon announce the aid package, which includes anti-tank weapons, interceptors and munitions for Patriot and other air defence systems.
It came as he met Ukrainian defence minister Rustem Umerov at the Pentagon.
In a post to social media, Mr Zelenskyy said the "critical items" will strengthen troops and "improve our battlefield capabilities".
"We count on continued US assistance to strengthen Ukraine’s defence and enable us to effectively counter Russian aggression and protect our people against Russian terror," he said.
