Putin issued a warning to Ukraine not to deploy the largely internationally outlawed cluster munitions that were shipped recently by the United States. “I want to say that Russia has sufficient reserves of various types of cluster munitions,” Putin said in a video clip released by Russian state TV. Russia did not want to use this resource, he added. “But of course, if it is used against us, then we reserve the right to take congruent actions.” The bombs, which explode above the ground, spread projectiles over a wide area. Because many of them often do not explode immediately, they, like mines, pose a danger to civilians even after hostilities have ended. Will this be a disaster for Ukraine ?
