MOSCOW, October 13. /TASS/. All proposals for a maritime truce lack clear guarantees that weapons will not be supplied to Ukraine by sea, and that Moscow will be able to export grain and oil via the Black Sea freely, Foreign Ministry Spokeswoman Maria Zakharova said.

"It is noteworthy that all the aforementioned proposals lack an understanding of the mechanisms that would guarantee that weapons will not be supplied to Ukraine by sea, while Russia will be able to carry out its exports, including agricultural produce and oil, unhindered via the Black Sea," the diplomat noted.
