Overview

• Ukraine said a Russian strike on a substation in Slavutych cut external power to the Chornobyl site, forcing the confinement structure onto emergency generators before power was later restored, according to the IAEA.
• The Russian‑occupied Zaporizhzhia nuclear plant remains off Ukraine’s grid and on diesel back‑up, with Zelenskyy calling the situation critical and the IAEA warning the arrangement is not sustainable.
• The Wall Street Journal and Reuters reported the U.S. will provide intelligence to support Ukrainian long‑range strikes on Russian energy infrastructure, as the Kremlin claimed such assistance is already occurring.
• French forces boarded and detained crew from a Russia‑linked ‘shadow fleet’ tanker off western France that is under investigation over suspected drone launches tied to disruptions in Denmark.
• Ukraine reported 158 combat clashes on Oct. 1 as Russia launched 49 Shahed‑type drones and several ballistic missiles overnight, with most intercepted, and Kyiv announced the return of 185 soldiers and 20 civilians in a prisoner swap.
