A localized ceasefire, facilitated by the IAEA, began to allow for repairs to a damaged backup transformer near the Zaporizhzhya nuclear power plant. The Health Cluster's humanitarian response and funding snapshot for January to September 2026 was released. Research terms of reference were published for a longitudinal study of Ukrainian refugees in Europe.

Attacks on energy infrastructure and damaged housing risk re-displacing Ukrainians this winter, particularly those who had previously returned home. Funding for the humanitarian response remains well below requirements, potentially impacting critical aid delivery.

At least 328 civilians were killed and 2,105 injured in September 2026, marking an 85% increase in casualties compared to September 2025. Over 6.7 million Ukrainians have sought refuge across Europe since February 2022, with many benefiting from the EU's Temporary Protection Directive.

The specific locations of the highest civilian casualties in September 2026 are not detailed. Information on the current status of the Zaporizhzhya nuclear power plant's main power supply is not covered.
