MADRID (Reuters) - Ukrainian President Volodymyr Zelenskiy says he is making progress in persuading the West to supply Ukraine with fighter jets - with U.S.-built F-16s flown by several NATO nations in particular focus.

On a tour of European capitals this week he received pledges from British Prime Minister Rishi Sunak and Dutch PM Mark Rutte to help build a "jets coalition", although both leaders have stopped short of saying they will send planes.
