Kiev warned that Russian forces are pushing additional ships to the Black Sea loaded with Kalibr missiles, raising the risk of a major missile attack on Odessa. Kiev was forced, due to the leak of classified US documents, to modify some of its military plans before carrying out a counterattack.
Russian forces occupy swathes of Ukrainian territory in a war that broke out in February last year. U.S. officials are trying to determine the source of the leak, including those related to Ukrainian air defenses and Israel's Mossad.
