Solidarity Against Terrorism Day is observed in Russia every September 3 to commemorate the tragic events of the Beslan school siege in 2004. On this day, the nation remembers the victims of terrorism, particularly the 396 people who lost their lives, including 156 children, during the crisis at Beslan's Secondary School No. 1, where over 1,000 hostages were held by terrorists. The siege lasted three days and ended with a violent assault by federal forces, resulting in numerous casualties. Established in 2005 under the law On Days of Military Glory of Russia, this memorial day honors not only the victims but also enforcement officers who died in the line of duty. Activities on this day typically include memorial services and moments of silence to reflect on the impact of terrorism.
