Ukrainian President Volodymyr Zelensky said Kyiv’s international partners have agreed to wait until 1 September for Russia to signal its readiness for a bilateral meeting that could open a new channel for negotiations. Zelensky added that if Moscow fails to respond by Monday, Ukraine will seek a coordinated reaction from its allies. He also urged partner governments to ratify security-guarantee agreements that Ukraine has negotiated with them. Separately, Foreign Minister Andrii Sybiha announced that the United Nations Security Council will convene an emergency session on 29 August at 22:00 Kyiv time to discuss what he described as another large-scale barrage of Russian missile attacks on Ukrainian territory.
