The United Nations Security Council should impose a comprehensive embargo on all military assistance against all warring factions in Afghanistan, Human Rights Watch urged today. In this report, Human Rights Watch accused Pakistan, Iran, and Russia of providing military support to Afghan factions with a long record of committing gross abuses of human rights. Other states in the region have also contributed to the ongoing war. The 55-page report details the nature of military support provided to the warring parties; the major transit routes used to move arms and other equipment; the suppliers; the role of state and nonstate actors; and the response of the international community. Human Rights Watch conducted research on military assistance to the Taliban and the United Front over a two-year period, traveling to both Kabul and areas of Afghanistan under United Front control, as well as Kazakhstan, Tajikistan, Kyrgyzstan, and Pakistan, and interviewing government officials, members of the diplomatic community, military officers, civil servants, journalists, academics, and others.
