US 'Appalled' at Iran's Alleged Drowning of Afghan Migrants Ayaz Gul ISLAMABAD, PAKISTAN - The United States has denounced as "appalling" reports that Iranian border guards tortured and drowned dozens of migrants from Afghanistan last week to prevent their entry into Iran. "We encourage the Afghan authorities to undertake a full investigation and to seek to hold those perpetrators accountable," U.S. Secretary of State Mike Pompeo said Wednesday at a news conference. Afghan officials and survivors say a group of about 60 men from their western Herat province was being smuggled into Iran before that country's border guards detained and later forced all of them into the Harirud River this past Saturday. The Kabul Foreign Ministry said Wednesday that Tehran has agreed to jointly investigate the incident to determine the "facts and identity of the perpetrators." On Sunday, Iranian Foreign Ministry spokesman Seyed Abbas Mousavi in a statement refuted the charges, while expressing sympathy with the families of the victims. "This incident has occurred on Afghan soil, and the Islamic Republic of Iran's Border Police has denied that any happening in relation to this has taken place on the soil of our country," Iranian media quoted Mousavi as saying. .
