NATO Secretary General Mark Rutte said he considered the sometimes harsh criticism of German Chancellor Olaf Scholz by Ukrainian President Volodymyr Zelenskiy to be unjustified, news wire DPA reported. Although Germany has been a vital ally of Ukraine, its hesitation in providing long-range Taurus cruise missiles has been a source of frustration in Kyiv, which is battling a foe armed with a powerful array of long-range weaponry. "I have often told Zelenskiy that he should stop criticising Olaf Scholz, because I think it is unfair," DPA quoted Rutte on Monday as saying in an interview.
