More and more, UNAMIR's peacekeeping troops were being attacked. Countries began to pull their soldiers out of Rwanda. Some members of the United Nations Security Council, like the United States, argued strongly that the UN should take "all" of its peacekeeping troops out of Rwanda. Eventually, the Security Council decided to decrease the number of troops UNAMIR was allowed to have. On April 21, 1994, as the genocide was spreading across Rwanda, the Security Council decreased the number of allowed UNAMIR troops from 2,548 to 270 a decrease of almost 90%.
