Russia's Emergency Ministry conducted a nationwide test of its alert system this morning, October 1st, 2025, between 10:05 AM and 11:05 AM UTC, broadcasting emergency signals and interrupting television channels across the country. This nationwide alert test occurred as Ukrainian drones attacked the Suhodolnaya oil pumping station in the Rostov region overnight, halting oil transportation, according to ASTRA sources. NASA satellites also recorded fire signatures at the site. Over the past hour, President Volodymyr Zelensky of Ukraine acknowledged the Day of Defenders of Ukraine by meeting with wounded soldiers and medics, presenting state awards to members of the Land Forces, Territorial Defense Forces, the 138th Special Purpose Center, and the Airborne Assault Forces. Zelensky stated, "Every attempt, every one, to conquer Ukraine ended only with Ukraine being reborn. All attempts to erase Ukraine and Ukrainians ended with the enemy empires crumbling. Ukraine survived not just one person who tried to wipe out our people from the world. Ukraine survived all of them who wanted to. Ukraine will stand up and now against this Russia, without a doubt it will stand up. We will definitely protect our state." The drone attack on the Suhodolnaya oil pumping station in the Rostov region, which ASTRA reported sources confirmed, involved at least 10 Ukrainian drones. The attack resulted in the cessation of oil transportation from the station. OSINT researcher GirkinGirkin was the first to note the incident, with NASA satellites confirming fire signatures. Previous reports from October 1st, 2025, indicated significant drops in Russian advance rates and ongoing gasoline shortages, with Ukrainian drone strikes having previously shut down 38% of Russia's oil refinery capacity. The Russian Emergency Ministry's nationwide alert test initiated around 10:05 AM UTC, with special announcements interrupting TV channels. Eyewitnesses in various cities documented the alerts. In military developments, the Ukrainian Air Force had reported missile launches towards the Sumy Region at 7:05 AM UTC and enemy tactical aviation activity in the eastern direction between 5:35 AM and 6:35 AM UTC on October 1st, 2025, utilizing guided aviation bombs against the Donetsk region.
