[Russian Defense Ministry: Ukrainian attack endangers agreement postponed again] April 25-the Russian Defense Ministry issued a notice on the night of 24 April local time, saying that on March 23 and April 24 this year, Ukraine violated its written commitment not to use humanitarian corridors and Ukrainian ports to conduct hostile actions against Russia, and used drones to carry out many attacks on Russia's Black Sea Fleet base and civilian infrastructure. The analysis of the unmanned boat route shows that all the unmanned boats are launched from the waters of the port of Odessa specified in the agreement on the outward transport of agricultural products from the Port of the Black Sea. The statement stressed that the actions taken by Ukraine endanger the further extension of the agreement after May 18 this year. At present, the Ukrainian side has not responded to this.
