NEW: Ukraine reportedly ordered a temporary ceasefire along the entire front from September 5–8, timed for the Witkoff-Kushner visits to Moscow and Kyiv. Multiple brigades confirmed receiving "respond only" orders. But Russia never agreed to match it — overnight Russian drones and missiles hit Kyiv, Kharkiv, and destroyed a hypermarket in Mykolaiv. By morning the General Staff said defensive operations continue "in full" because a ceasefire "cannot be unilateral." Zelensky had separately halted Ukrainian airstrikes on Russian territory while the envoys travel. The pause was a Ukrainian initiative, not a negotiated deal.
