A powerful early-morning blast levels an apartment building on Kashirskoye Street, Moscow, killing 118 people. Russian Prime Minister Vladimir Putin and Moscow’s mayor Yuri M. Luzhkov blame Chechen terrorists. [New York Times, 9/13/1999; BBC, 9/13/1999] Another Moscow apartment building was bombed on September 9, killing nearly 100 (see September 9, 1999). Later in the month, explosives will be found in an apartment building in the nearby city of Ryazan. The Russian government will initially declare it a foiled bombing until the suspects arrested turn out to be FSB agents. The government will then claim it was merely a training exercise (see September 22-24, 1999). This will lead some to suspect that all three apartment bomb incidents this month were false flag attacks by the FSB (see March 6, 2002, December 30, 2003 and January 2004).
