United Nations Security Council Resolution 83, adopted on June 27, 1950, determined that the attack on the Republic of Korea by forces from North Korea constituted a breach of the peace. The Council called for an immediate cessation of hostilities and for the authorities in North Korea to withdraw their armed forces to the 38th parallel. They also noted the report by the United Nations Commission on Korea that stated North Korea's failure to comply with Security Council Resolution 82 and that urgent military measures were required to restore international peace and security.
