Russia's Defense Ministry claims a Ukrainian "saboteur group" blew up a segment of the Tolyatti-Odesa pipeline, the world's largest ammonia conduit, in Ukraine's Kharkiv region. Kyiv has not commented on the statement but previously it has said that the pipeline has come under repeated Russian shelling. Ammonia is a main ingredient in production of nitrate fertilizer, of which Russia is one of the world's leading producers.
