5) The Ryazan Test:
An apparent bomb was found on September 22rd, 1999
in an apartment building on New Settler's Street in
Ryazan, Russia. Although the police initially reported
that it was the work of Chechen terrorists, and preliminary
police lab tests showed the presence of explosives in
the device that were similar to the five other bombs
blamed on Chechen terrorists, the Ryazan police found
that the car used in planting the device traced back
to the the Russian Intelligence Service, FSB. Nikolai
Patrushev, the head of the FSB, then announced that
the incident in Ryazan had been nothing more than a
"training exercise" staged by the FSB to test
local vigilance and the bomb contained only harmless
sugar. But the chemical analysis was never released.
