The Russian government says that nearly 200 people were killed and some 500 wounded during the 10-day standoff. Communist and other nongovernmental sources put the death toll at more than 1,000. It was the worst violence in Moscow since the 1917 Bolshevik coup.
Following the 1993 violence, the parliament building underwent extensive renovation and today it is the seat of the Russian government. Yeltsin pushed through a new constitution in December 1993, giving the presidency sweeping powers that have been increased over the last three decades.
