Russian President Vladimir Putin said that the grain agreement will be called into question if the facts of the use of rubber corridors for terrorist attacks are established.

 However, as the Russian leader added, there is no such data yet.

 "But if the humanitarian corridors for the supply of grain to the poorest countries, although it does not go there, but this work was organized under this pretext. It turns out that the humanitarian corridors are used to carry out terrorist acts, then, of course, this will raise a big question further functioning of this corridor, but we do not have such data yet," he said at a press conference in Astana.

 Note that the grain agreement expires in November.
