In his book Darkness at Dawn David Satter reported that on 6 June 1999,[102] three months before the bombings, Swedish journalist Jan Blomgren wrote in Svenska Dagbladet that one of options considered by the Kremlin leaders was "a series of terror bombings in Moscow that could be blamed on the Chechens."[103][104] Satter also noted that on 22 July, the Moscow newspaper Moskovskaya Pravda published leaked documents about an operation, "Storm in Moscow", which, by organising terrorist acts to cause chaos, would bring about a state of emergency, thus saving the Yeltsin regime.[105]
Duma member Konstantin Borovoi said that he had been "warned by an agent of Russian military intelligence of a wave of terrorist bombings" prior to the blasts.[103]
