An estimated 3,000–5,000 Haitians were killed during the period of military rule. The coup created a large-scale exodus of refugees to the United States. The United States Coast Guard interdicted (in many cases, rescued) a total of 41,342 Haitians during 1991 and 1992. Most were denied entry to the United States and repatriated back to Haiti. Aristide has accused the United States of backing the 1991 coup. In response to the coup, the United Nations Security Council passed Resolution 841 imposing international sanctions and an arms embargo on Haiti.
