Ukrainian President Volodymyr Zelenskyy arrived in the United States ahead of talks with President Donald Trump on Tuesday, saying Kyiv's top priority was securing stronger air defense and strategic cooperation as Russia intensified attacks.

"Our number-one priority is anti-ballistic defense and strategic cooperation with America. Peace needs to be brought closer," Zelenskyy said in a post on X after arriving in the US.

The two leaders are due to meet at the White House before attending a tribute to Senator Lindsey Graham, a staunch supporter of Ukraine, who passed away earlier this month.
