Polish Prime Minister Donald Tusk stated on September 11th, 2025, that Poland will defend its territory and treat any attackers adequately, following a violation of Polish airspace by Russian drones. "Everyone who wants to attack Poland will be treated adequately, as it was September 10," Tusk said after a National Security Council meeting, characterizing Moscow's actions as provocations targeting not only Poland. Meanwhile, a Russian oil depot in Kardymovo, Smolensk region, was hit by drones overnight, approximately 285km from the front line, according to multiple reports. The strikes on the Kardymovo oil depot, located at coordinates 54.8808377,32.4323010, occurred within the reporting window of 9:01 PM to 11:01 PM UTC on September 11th, 2025. This follows earlier reports from the previous reporting window (9:31 PM to 10:01 PM UTC) of Ukrainian drone activity targeting the Smolensk region, specifically the Kardymovo oil depot, where damage was reported to a tank park containing 10,900 cubic meters of light petroleum products. Prime Minister Tusk's comments indicate a firm stance against airspace violations, referencing a previous incident on September 10th. The Ukrainian Air Force had previously noted a threat of ballistic weapons. The context of these events includes heightened regional tensions, with Poland announcing a full border closure with Belarus effective September 12th, a move Russia's Foreign Ministry spokesperson Maria Zakharova criticized as "escalation."
