British rock star Rod Stewart on June 17 defended his support for Ukraine after he was booed at a show in Germany after an image of Ukraine's flag and President Volodymyr Zelenskiy appeared on screens in the stadium. Stewart, 79, has been outspoken in his support for Ukraine, which has included help for a family of seven fleeing Russia's invasion. While performing in Leipzig on June 14, the display of the Ukrainian flag and an image of Zelenskiy was met by loud boos, shouts, and whistles. Steward told Britain's PA news agency that his support for the Ukrainian people will continue. "[Russian President Vladimir] Putin must be stopped," he said.
