Such accusations were voiced by the Russian Ministry of Defense and Russian Ambassador to the UN Vasylii Nebenzia, as well as written by Russian media and anonymous social media channels. It is not true.

UN spokesman Martin Griffiths confirmed that on the night of October 29, at the time of the attack, there were no ships in the humanitarian grain corridor. Russia accuses Ukraine of using a humanitarian corridor for drone attacks without providing any evidence. The Ukrainian side did not claim responsibility for the incident, although it did not unambiguously deny involvement in the attack.

On July 22, through the mediation of the UN and Turkey, Ukraine and Russia signed an agreement under which a safe maritime corridor was agreed between three Ukrainian ports and Turkish territorial waters. To control the implementation of the agreement, a Joint Coordination Center (JCC) was established in Istanbul, which, in turn, includes four groups of 8 inspectors. Russia, Ukraine, Turkey and the UN each provided two inspectors. Monitoring groups check all ships that enter Turkish waters along the corridor from Ukraine. Empty ships returned to Ukraine are also checked to prevent the transport of weapons or unauthorized goods to Ukraine by ships and the illegal transportation of people. On November 02, four days after withdrawing from the agreement, Russia rejoined the agreement.

Russia, long before the attack of the fleet in Sevastopol, was preparing to withdraw from the grain deal. The attempt to block the grain corridor is a part of Putin's plan for a new phase of the war to deplete Ukraine.
