More than 240 [Russians died in the autumn of 1999] in a wave of bombings that destroyed three blocks of flats, two in Moscow and one in the town of Volgodonsk. The Russian authorities were swift to lay the blame at the door of Chechen separatists. But no supporting evidence has emerged. Two men from the Caucasus were convicted of involvement after a closed trial this year, but it was widely denounced as a charade. Instead a growing body of proof has surfaced that links the bombings ... to the FSB - the revamped KGB. Independent investigators, including several MPs, who have sought to look into the case have been intimidated, arrested or beaten. Analysts and investigators claim that President Vladimir Putin, who was FSB chief until August of that year and subsequently prime minister, must know the truth. Lilia Shevtsova, a senior associate with the Carnegie Endowment for International Peace, said: He would know not just what happened but who the suspects were. The truth will not damage him because it won't be told until after he is gone." The 1999 bombings proved to be Mr Putin's political making. He positioned himself as a strongman who would crush the Chechen rebels and restore order to the ailing country. Riding a wave of nationalist fervour, in eight months he went from being a virtual political unknown to winning the presidency by an easy margin.
