The Moscow bombings were a terrorist attack that targeted employees of the Soviet Ministry of Defense. The bomb was placed in a white truck packed with 680 pounds of explosives. The resulting explosion was the largest detonated in the city after the Second World War and claimed up to 217 lives; the Soviet Supreme Marshal included. An estimated 950 million rubles in damage was inflicted.
The bomb went off at 1:30 PM without warning. Survivors of the blast reported hearing a big bang and then seeing a bright light, before the building started to collapse. The entire front section of the ministry building collapsed, as well as severe structural damage to the buildings around it. Rescue workers had trouble digging out victims of the blast out from the rubble due to the fact that the concrete the ministry was made of had been designed to withstand an aerial bomb, however gave way at a blast this close. Eventually bulldozers and small detonations had to be used to clear large chunks of rubble.
The Soviet Militia was quick to respond, flooding to the sight of the bomb which was flooded with confusion. At first nobody knew what exactly happened, though it became clear that an EXTOL bomb was responsible. After the bomb went off, EXTOL began rapid expansion of their troop placements, into South America and Africa. The Soviet Ministry of Defense issued a brief statement after the bomb "vowing revenge"
