KYIV, Dec 18 (Reuters) - Ukraine's President Volodymyr Zelenskiy said on Sunday the world still had heard his call for peace despite soccer governing body FIFA's decision to decline to allow a video message to be broadcast ahead of the soccer World Cup final in Qatar.Zelenskiy had asked for the video to be broadcast, including his call to hold a global peace conference to help resolve the war triggered by Russia's invasion of Ukraine."Even though FIFA blocked this message from being aired at the stadium before the final game in Qatar, the world still heard our appeal," Zelenskiy said in his nightly video address to Ukrainians.The worst that can happen is a red card - and not the red button," he said, alluding to the possibility of a nuclear strike.Russian news agencies reported that Kremlin leader Vladimir Putin had "warmly congratulated" Argentine President Alberto Fernandez on Argentina's victory over France in the World Cup final at Doha's Lusail stadium on Sunday."
