Ukraine's Nato-led allies have announced deliveries of advanced air defence weapons to Kyiv, after a spate of Russian missile strikes.

The weaponry promised by the UK, Canada, France and the Netherlands includes missiles and radars. The US earlier made a similar pledge. One high-tech system from Germany is already in Ukraine.

The pledges come as Ukraine's allies from 50 countries meet at NATO headquarters in Brussels.

Kyiv hailed the summit as "historic".
