What Ukraine's breakthrough in Zaporizhzhia means going forward

Ukraine claims to have made a significant breakthrough in its counteroffensive, saying its forces have 'decisively breached' Russia’s first defensive line in the southern Zaporizhzhia region. Just a week ago, Ukrainian troops reclaimed Robotyne, a key village on the Zaporizhzhia frontline. The latest reports of an advance would mark a significant boost for Ukraine amid concerns from some of its allies that the counteroffensive is faltering.
