This is the moment the leg of Russian president Vladimir Putin was seen 'twitching suspiciously' as he bid farewell to Donald Trump.
Kremlin footage captured the Russian leader’s knee jolting repeatedly as he stood alongside his US counterpart at the end of their brief exchange following a joint press conference at the summit in Alaska.
The pair, flanked by security teams and aides, spoke for a short time, with a translator stepping in to assist their conversation.
Video clips shared online showed the Russian leader repeatedly dipping one knee as he stood beside the 6ft 3in former president at Elmendorf-Richardson air base in Anchorage - before departing without agreeing to a ceasefire in Ukraine.
But the unusual movements was seized by eagle-eyed Ukrainians, who ridiculed the 72-year-old’s fidgeting and speculated about the state of his health.
