President Zelensky has threatened Putin with a “tough response” if Russia continues to interfere with Ukraine’s grain export corridor. A deal was brokered on July 22 between Turkey and the UN to allow grain ships to pass through the area, however, Moscow has recently extricated itself from the agreement.Ships are continuing to be loaded and move out of ports thanks to Turkish cooperation.Putin withdrew from the deal claiming he could not guarantee the safety of civilian ships after his fleet were attacked in the Black Sea.Speaking in his Tuesday night address the Ukrainian President said: “A reliable and long-term defence is needed for the grain corridor.”Russia must clearly be made aware that it will receive a tough response from the world to any steps to disrupt our food exports.
