Ukrainian forces launched a major attack in the southern Zaporizhia region on Thursday. There was no sign of a decisive breakthrough in an operation that carries great risks for Kiev.
U.S. officials and military analysts said a long-awaited major Ukrainian counteroffensive appeared to be underway. Ukraine is expected to stage a multi-pronged assault along a front of hundreds of kilometers, focusing on a swath of the Zaporzhia and Donetsk regions. The Russian Defense Ministry said Thursday that its forces had foiled a Ukrainian attack.
