Ukraine's President Volodymyr Zelenskyy on Monday asked Western leaders meeting in Latvia, including British Prime Minister Rishi Sunak, to supply a wide range of weapons systems.

"I ask you to increase the possibility of supplying air defense systems to our country, and to help speed up the relevant decisions to be taken by our partners," Zelenskyy asked Sunak during his speech on a video link, addressing a meeting in Riga of leaders of countries in the Joint Expeditionary Force.

The British-led grouping, configured to respond rapidly to crises in the Northern Europe, is made up of Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, the Netherlands, Norway, and Sweden.

While Western allies, led by the United States, have been supporting Ukraine with funding, military training and deliveries of air defense systems and other weaponry, Kyiv has said still more was needed to sustain its campaign against Russia.
