On 1 September 2004, Muslim Chechen terrorists took 1,200 children and adults hostage in a school in Beslan, North Ossetia.
The building was surrounded by Russian special forces, and for two days there was a tense stand-off. On the third day, all hell broke loose after a sudden explosion, and the siege became a bloodbath. In all, nearly 400 people were killed, including 186 children. Many more were injured in one of modern Russia's darkest days.
