After Ukrainian drone attacks on facilities in St. Petersburg on the opening day of the St. Petersburg International Economic Forum (SPIEF), Russia's current response strategies require fundamental changes. Strike on St. Petersburg Oil Terminal Had Been Anticipated Ukrainian forces attacked the St. Petersburg Oil Terminal and a military vessel in Kronstadt with drones. Volodymyr Zelensky did not need a fortune teller to understand that the strike should come precisely on the opening day of the St. Petersburg International Economic Forum. Russian President Vladimir Putin is scheduled to address the forum tomorrow, and a burning terminal provides an ideal image capable of causing concern not only for him but also for the many guests attending the event.

One person was killed and several others were injured in attacks on Kuwait International Airport, while airport facilities sustained significant damage and flight operations were suspended, according to Kuwait's Ministry of Foreign Affairs and the Directorate General of Civil Aviation. Both agencies accused Iran of carrying out the attacks. The strikes on Kuwait came after the United States and Iran exchanged attacks overnight. The U.S. military stated that it had disabled an empty oil tanker heading toward Iran's Khark Island and later carried out strikes on Iran's Qeshm Island "in self-defense." The Islamic Revolutionary Guard Corps (IRGC) claimed that Iran responded by launching missiles and drones at a U. S. vessel, the headquarters of the U.S. Navy's Fifth Fleet in Bahrain, as well as a U. S. airbase and helicopters in a Middle Eastern country.
