Ukraine will train Polish forces on counter-drone warfare within Ukraine, a development announced within the last 14 minutes of the reporting window, September 11th, 4:16 PM UTC. This initiative follows recent drone incursions into Polish airspace, prompting heightened security concerns. This training arrangement was highlighted in a report referencing Ukrainian President Volodymyr Zelenskyy's call for allies to rethink air defense strategies after a recent drone incident in Poland. The specifics of when this training will commence or the exact number of Polish forces involved were not detailed in the provided sources. Separately, reports from social media indicated that individuals with ties to security services in Ukraine and potentially Russia were advised by family members to urgently gather supplies and evacuate areas outside cities, suggesting a perceived escalation or immediate threat. One post mentioned a father working for Facebook being called to an urgent meeting and later advising family to prepare for two weeks, while another cited a father working for the SBU (Security Service of Ukraine) giving similar instructions. These events occur in the context of ongoing military aid to Ukraine. Sweden recently delivered its 20th military aid package, valued at $836 million, which included 18 Archer howitzers and classified systems. Meanwhile, the European Union's General Court annulled the European Commission's approval for Hungary's Rosatom-built Paks II nuclear power plant project on September 11, 2025, citing a failure to justify bypassing EU procurement rules.
