Moscow - (AFP) - The Russian army said Monday that it wants "obligations" from Ukraine not to use the grain export corridor for military purposes, after the drone attack on its fleet in Crimea and the suspension of the agreement to export grain.

"There is no way to guarantee the safety of anything in this region until Ukraine makes additional commitments not to use this road for military purposes," the Russian Ministry of Defense wrote on Telegram.

The ministry called on the United Nations, the guarantor of the Ukraine grain export agreement signed in July, to help "obtain guarantees from Ukraine that the humanitarian corridor and Ukrainian ports designated for the export of agricultural products will not be used for hostile acts against Russia."

Moscow suspended its participation in the grain transfer agreement after it accused Ukraine of launching a "major" attack with drones on its Black Sea fleet in Crimea, which Russia annexed in 2014.

The Russian military said the attack, which Moscow attributed to Ukraine with the help of British specialists, was carried out in part from the sea lane used to transport grain.

"Pending clarification of the situation resulting from the terrorist act committed by Ukraine on October 29 (...) the security corridor will be suspended," he added.

"The movement of ships along the security corridor is unacceptable, as the Ukrainian leadership and the leadership of the Ukrainian army use it to carry out combat operations against Russia," he added.
