A number of viral posts on social media have claimed that a Canadian sniper, dubbed "the world's deadliest sniper", was killed within hours of arriving in Mariupol, Ukraine, where he had gone to fight. However the man, nicknamed Wali, is still alive and well. He told the FRANCE 24 Observers team that he thinks the disinformation around his death serves to dissuade foreign fighters from going to Ukraine.
Col. Oleksandr "Grey Wolf" Oksanchenko, a decorated Ukrainian pilot, was killed in combat on Feb. 25.
Ukrainian President Volodymyr Zelensky awarded him posthumously with the title of Hero of Ukraine, along with 11 other military service members.
Unconfirmed reports hold that an unidentified pilot, who has come to be called the "Ghost of Kyiv," downed six Russian planes on the first day of Russia's invasion of Ukraine. We do not find evidence that this was Oksanchenko.
It's uncertain how the Ghost of Kyiv tale originated, but we know that Ukraine's military reported on Feb. 24 that at least six Russian planes and two helicopters had been downed. Crediting Ukrainian military, CNN and NBC soon reported five Russian planes and one helicopter had been shot down. Russia's defense ministry denied the report, according to Reuters, and said that Ukraine's air force defenses had been "suppressed."
Ukraine's official Twitter account, meanwhile, promoted the Ghost of Kyiv narrative with a video that suggested the mystery pilot could have been responsible for as many as 10 downed Russian aircraft by Feb. 26. That video, too, included footage from a video game.
PolitiFact did not receive a response from Zelensky's administration about Oksanchenko and the Ghost of Kyiv claim.
Finding no conclusive information tying Oksanchenko to the Ghost of Kyiv, we rate this claim False.
China's government is amplifying debunked claims about non-existent U.S. biological weapons labs in Ukraine, bringing the falsehoods back into the spotlight on social media.
Our ruling
A spokesperson for the Chinese government said the U.S. has biolabs in Ukraine.
The claim originated with the Russian government and has been previously debunked by U.S. government officials and weapons control advocates. Following Zhao's March 9 remarks, U.S. government officials strongly refuted the claims again, saying the false narrative was being used to lay the groundwork for further violence in Ukraine.
