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

Trump welcomed Zelenskyy to the White House late on Tuesday morning local time, ahead of the funeral for Senator Lindsey Graham, a staunch supporter of Ukraine, who passed away earlier this month.

Images taken from behind the fences at the White House showed Zelenskyy exiting a car ready to enter the building.

The Ukrainian president was expected to conduct a short meeting with his US counterpart, likely without reporters present, according to unnamed sources briefing news agencies including Reuters.
