Ukraine's President Volodymyr Zelensky speaks during a joint news conference with Greece's Prime Minister Kyriakos Mitsotakis at Maximos Mansion in Athens, Greece, Monday, Aug. 21, 2023 (AP)

"Everyone understands who is involved," Ukrainian President Volodymyr Zelensky stated, on Thursday, as he alleged that Kiev had nothing to do with the accident in Russia's Tver area of a jet carrying Wagner Group private military company (PMC) head Yevgeny Prigozhin.

Zelensky told reporters "We have nothing to do with this. Everyone understands who is involved," according to UNIAN news agency.

Late last night, on Wednesday, the Federal Air Transport Agency Rosaviatsia confirmed Prigozhin was aboard the private jet that crashed that evening.

Prigozhin's name was among the Embraer-135 (EBM-135BJ) passengers, in addition to Proposition Sergey, Makaryan Evgeniy, Totmin Aleksandr, Chekalov Valeriy, Utkin Dmitriy, and Matuseev Nikolay.

"Crew members: commander [pilot] Levshin Aleksei, second pilot Karimov Rustam, and flight attendant Raspopova Kristina," were also on board the flight, the agency detailed on Telegram.

Russia’s Ministry of Emergency Situations confirmed that a private plane on its way from Moscow to St. Petersburg crashed in the Tver Region on Wednesday, announcing that the incident killed all 10 people aboard.

In turn, the US President has expressed he was "not sure" what caused the crash but revealed he was "not surprised" by the news.

He steered clear of pointing any fingers at Russian President Vladimir Putin when asked and carefully responded that he did not have enough facts to answer.
