Putin spoke after The New York Times, The Washington Post and German media published stories last week citing unidentified U.S. and other officials as saying there was evidence Ukraine, or at least Ukrainians, may have been responsible. The Ukrainian government has denied involvement.
Germany’s Die Zeit newspaper and German public broadcasters ARD and SWR reported that investigators believed five men and a woman used a yacht hired by a Ukrainian-owned company in Poland to carry out the attack. German federal prosecutors confirmed that a boat was searched in January but have not confirmed the reported findings.
