The drivers of two vehicles reportedly wore federal
military uniforms and carried official passes which allowed them through three successive military checkpoints on their way to the headquarters building. A guard at the fourth and final checkpoint attempted to inspect the vehicles, and began firing on the vehicles as they drove through the checkpoint towards the building. The explosion by the equivalent of a ton of
dynamite brought down the roof and floors of the four-story building. The first reports mentioned as few as two dead. Ultimately, Chechen officials said 83 people were killed (48 on the spot) and 210 were injured. Several Chechen administration officials were injured in the attack, including
Deputy Prime Minister Zina Batyzheva (seriously wounded) and Chechen
Security Council Secretary Rudnik Dudayev. The head of the pro-Russian administration in Chechnya,
Akhmad Kadyrov, and his
Prime Minister,
Mikhail Babich, were not in the building at the time. == Responsibility ==
