Ukraine: counting the cost of a long war – podcast

President Zelenskiy has urged G7 leaders to urgently send more heavy weapons to Ukraine to bring the war to an end before winter. But, as Dan Sabbagh reports, there is no clear resolution in sight

World leaders are gathering in Madrid today for the Nato conference, and one issue will loom above all else: the war in Ukraine. The conflict has been described as the biggest security challenge to the west since 9/11 and, alongside practical considerations of military aid, leaders are desperate to project an image of unity.

The Guardian's Dan Sabbagh, who is in Madrid for the conference, has just returned from eastern Ukraine, where he witnessed the relentless shelling of Ukrainian troops. He talks to Michael Safi about a frontline that has come to resemble the battlefields of the first world war.
