A Russian military plane carrying a high-level delegation led by the head of the Main Directorate of the General Staff of the Russian Armed Forces (GRU), Admiral Igor Kostyukov, arrived in Israel on Saturday night, on an unusual visit. This is what journalist Amichai Stein reported, citing two sources familiar with the situation, in the "Jerusalem Post". According to the publication, the Russian delegation held meetings with senior representatives of the Israeli Ministry of Defense. However, the purpose of the visit and the content of the negotiations are not officially disclosed. The unexpected arrival of the Russian military delegation to the country took place against the backdrop of a worsening situation in the Middle East and the uncertainty surrounding a possible new round of military conflict between the US, Israel and Iran. On Monday, the plane and the Russian delegation left Israel and headed for Abu Dhabi. There, Kostyukov and the accompanying Russian representatives are supposed to take part in negotiations on Ukraine mediated by the United States, scheduled for November 10-11.
