"Russia's Prigozhin Plane Crash Investigation Ignites International Controversy"

Russia has informed Brazil's aircraft investigation authority that it will not conduct an investigation into the plane crash that killed mercenary boss Yevgeny Prigozhin under international rules "at the moment." The Brazilian agency had expressed its willingness to join a Russian-led investigation if invited and held under international rules. However, Russia's aviation authority is not obligated to accept, and some former investigators argue that Brazil's participation is crucial for transparency. The flight was considered domestic, so it is not subject to international rules. The decision raises concerns about the transparency of the Russian investigation, as Brazil is the country where the plane was manufactured.
