Ukraine has intensified its attacks on Russian oil refineries, striking targets increasingly deep inside the country and forcing some facilities to cut production or shut down. Dozens of refineries have been hit, disrupting Russia's ability to produce petrol and diesel.

Sky News business and economics correspondent Paul Kelso examines Ukraine's escalating refinery campaign, the impact on Russia's fuel supplies and whether it can ultimately put pressure on the revenues helping fund Putin's war. #skynews #russia #ukraine #world SUBSCRIBE to our YouTube channel for more videos: http://www.youtube.com/skynews Follow us on X: https://twitter.com/skynews Like us on Facebook: https://www.facebook.com/skynews Follow us on Instagram: https://www.instagram.com/skynews Follow us on TikTok: https://www.tiktok.com/@skynews For more content go to http://news.sky.com and download our apps: Apple https://itunes.apple.com/gb/app/sky-news/id316391924?mt=8 Android https://play.google.com/store/apps/details?id=com.bskyb.skynews.android&hl=en_GB Why not listen to one of our podcasts?
