Ryazan Sugar (Hexogen)

Three large sacks of white granules, wired to a timer set for 5:30 AM, were found in the ground floor of a Ryazan apartment building on 22 September 1999—perhaps preventing yet another apartment bombing in a series that had terrorized Russians all month. FSB chief Nikolai Patrushev later told a TV reporter that these sacks contained nothing but sugar, which were being used in a test of public vigilance.
