I spoke with the Head of the Security Service of Ukraine, Oleksandr Poklad. Unfortunately, a Russian drone struck the central building of the Security Service of Ukraine on Volodymyrska Street in Kyiv, across from St. Sophia Cathedral. All emergency services are on the scene. Everyone affected will receive the necessary assistance. The drone was aimed directly at the office of the Head of the Security Service in that building. I instructed Poklad to deliver an appropriate, tangible response and, where possible, one that mirrors this strike, to the Russians once everything is ready. Our military will support this response. Glory to Ukraine!
