On 9 February 2000, a Russian tactical missile hit a crowd of people who had come to the local administration building in Shali, a town previously declared as one of the "safe areas", to collect their pensions. The attack was a response to a report that a group of fighters had entered the town. The missile is estimated to have killed some 150 civilians, and was followed by an attack by combat helicopters causing further casualties. Human Rights Watch called on the Russian military to stop using FAE, known in Russia as "vacuum bombs", in Chechnya, concerned about the large number of civilian casualties caused by what it called "widespread and often indiscriminate bombing and shelling by Russian forces". On 18 February 2000, a Russian army transport helicopter was shot down in the south, killing 15 men aboard, Russian Interior Minister Vladimir Rushailo announced in a rare admission by Moscow of losses in the war.
