A Russian missile attack in southeastern Ukraine on Tuesday killed at least 17 people and caused sweeping damage, officials said, as President Volodymyr Zelenskiy urged Kyiv's allies at a NATO summit to bolster Ukraine's defence industry.

The Ukrainian leader met with King Charles III and Prime Minister Keir Starmer on Monday, after the latest in a series of intensifying Russian strikes.

Ukrainian Foreign Minister Andrii Sybiha called on Kyiv's Western partners to respond to the attack. NATO leaders are currently in The Hague for an alliance summit, where President Volodymyr Zelenskyy hopes to secure more military support.
