CAIRO (AP) — The 15 officers who arrived at the prison in southern Yemen hid their faces behind headdresses, but their accents were clearly foreign — from the United Arab Emirates. They lined up the detainees and ordered them to undress and lie down. The officers then searched the anal cavity of each prisoner, claiming that they were looking for contraband cellphones.
The men screamed and wept. Those who resisted were threatened by barking dogs and beaten until they bled.
Hundreds of detainees suffered similar sexual abuse during the event on March 10 at Beir Ahmed prison in the southern city of Aden, according to seven witnesses interviewed by The Associated Press. Descriptions of the mass abuse offer a window into a world of rampant sexual torture and impunity in UAE-controlled prisons in Yemen.
The UAE is a key U.S. ally whose secret prisons and widespread torture were exposed by an AP investigation last June. The AP has since identified at least five prisons where security forces use sexual torture to brutalize and break inmates.
Yemen's war began in 2015, after Iranian-backed Houthi rebels took over much of the country's north. Saudi Arabia and the UAE are leading a coalition to fight the rebels, but UAE forces have overtaken wide swaths of territory, towns and cities in the south. The U.S. is backing the coalition with billions of dollars in arms, and partners with the Emiratis in anti-terrorism campaigns.
Emiratis have swept up hundreds of Yemeni men into a network of at least 18 hidden prisons on suspicion of being al-Qaida or Islamic State militants. The prisoners are held without charges or trials.
The AP first asked the Pentagon about grave rights abuses committed by the UAE one year ago. But despite well-documented reports of torture reported by the AP, human rights groups and even the United Nations, Marine Maj. Adrian Rankine-Galloway, a Pentagon spokesman, said the U.S. has seen no evidence of detainee abuse in Yemen.
Still, he called the allegations "disturbing" and said, "The United States take all allegations of abuse seriously, although we have no substantiating information at this time."
U.S. officials have acknowledged that American forces receive intelligence from UAE partners and have participated in interrogations in Yemen. But Rankine-Galloway said he could not comment on intelligence sharing with partners.
Reacting to the AP's report, the State Department called the allegations "disturbing" and called on the UAE to investigate.
"We call on all parties to the conflict, including the UAE, to treat prisoners and detainees humanely and to ensure that allegations of abuse are investigated quickly and thoroughly," the department said in a statement.
UAE officials did not respond to requests for comment, but the country's permanent mission to the United Nations in Geneva released a statement after publication claiming that the Yemeni government is in complete control of its prisons.
"The UAE has never managed or run prisons or secret detention centers in Yemen," the mission said.
But Yemen's interior minister has said he does not have authority over prisons and must ask for UAE permission to enter Aden, where witnesses documented much of the sexual torture.
Witnesses said Yemeni guards working under the direction of Emirati officers have used various methods of sexual torture and humiliation. They raped detainees while other guards filmed the assaults. They electrocuted prisoners' genitals or hung rocks from their testicles. They sexually violated others with wooden and steel poles.
"They strip you naked, then tie your hands to a steel pole from the right and the left so you are spread open in front of them. Then the sodomizing starts," said one father of four.
From inside the prison in Aden, detainees smuggled letters and drawings to the AP about the sexual abuse. The drawings were made on plastic plates with blue ink pen.
The artist told the AP that he was detained last year and has been in three different prisons. "They tortured me without even accusing me of anything. Sometimes I wish they would give me a charge so I can confess and end this pain," he said. "The worst thing about it is that I wish for death every day and I can't find it."
He spoke on condition of anonymity for fear of further abuse.
The drawings show a man hanging naked from chains while he is being electrocuted, another inmate on the floor surrounded by snarling dogs as several people kick him, and graphic depictions of anal rape.
"Naked after beating," one Arabic caption says. Another drawing shows a man's rectum being forced open.
"This is how they search the prisoners," the caption reads.
Of the five prisons where the AP found sexual torture, four are in Aden, according to three Yemeni security and military officials who spoke to the AP on condition of anonymity for fear of retaliation.
One is at the Buriqa base — the headquarters for the Emirati forces. A second is at the house of Shallal Shaye, the Aden security chief closely allied with the UAE, and a third is at a nightclub-turned-prison called Wadah. The fourth is at Beir Ahmed, where the March atrocities occurred.
U.S. personnel have been seen at the Buriqa base, along with Colombian mercenaries, according to two prisoners and two security officials. The detainees could not say whether the Americans, some of whom wear military uniforms, are members of the U.S. government or mercenaries.
But it is the UAE that has taken the lead in southern Yemen.
The humiliation of the entire prison population in March may have been triggered by a series of hunger strikes among prisoners, who are held for months or years. At least 70 detainees were ordered released earlier this year by state prosecutors but most remain in detention. The Yemeni government has said that it has no control over the UAE-run prisons and Hadi has ordered an investigation into reports of torture.
The incident in March began when soldiers opened cells at 8 a.m., ordered all detainees out to the prison yard, then lined them up and forced them to stand under the sun until noon. When the Emirati force arrived, the detainees were blind-folded, handcuffed and led in groups or individually into a room. The Emiratis told the victims to undress and lie down — and then spread their legs open, touched their genitals and probed their rectums.
"You are killing my dignity," one prisoner was heard crying. A second screamed to the Emiratis, "Did you come to liberate us or strip our clothes off?"
The Emiratis shouted back: "This is our job!"
One prisoner said that when the Emiratis forced them to stand naked, "All I could think of was Abu Ghraib" — referring to the prison outside Baghdad where U.S. soldiers committed abuses against detainees during the Iraq war.
"They were searching for mobile phones inside our bodies," another witness told the AP. "Do you believe this! How could anyone hide a phone in there?"
In the same city, at the UAE-run prison inside the Buriqa military base, two prisoners told the AP they think American personnel in uniform must be aware of the torture - either because they have heard screams or seen marks of torture. Prisoners said that they have no knowledge of Americans being directly involved in the abuse.
"Americans use Emiratis as gloves to do their dirty work," said one senior security official at the Riyan Prison in the city of Mukalla. He spoke on condition of anonymity because of security concerns.
Two other security officials, who were once close to the Emiratis, said that mercenaries including Americans are present at all the Emirati military camps and sites, including the prisons. Their mission is mainly to guard.
The father of four said that sometimes the screaming from the beatings is so intense that he can feel his cell shake.
"It's beyond imagination," he said.
A former security chief who himself was involved in torturing detainees to extract confessions told the AP that rape is used as a way to force detainees to cooperate with the Emiratis in spying.
"In some cases, they rape the detainee, film him while raping, use it as a way to force him to work for them," he said. He spoke on condition of anonymity, because of security concerns.
Based on the AP investigation last year, the House of Representatives voted on May 24 to require Defense Secretary Jim Mattis to determine whether U.S. military or intelligence personnel violated the law in interrogations of detainees in Yemen.
The House adopted the measure as part of the 2019 defense authorization bill, which is still under consideration by the Senate. The amendment was sponsored by Rep. Ro Khanna, a Democrat from California. The Defense Department would have to submit a report within 120 days to Congress.
Khanna called the AP's report Wednesday "a shocking revelation of the ongoing human rights abuses happening in Yemen."
"Now, with greater urgency than ever before, we need the Pentagon to launch an investigation and determine whether our nation has been involved in torturing prisoners in Yemen," he said.
Amnesty International said it had also documented "systematic grave violations" in UAE-run prisons in Yemen. Responding to the AP report, the group said it was "shocking" that U.S. officials "continue to dismiss these credible allegations."
Kristine Beckerle, a researcher for Human Rights Watch in Yemen, said her group had also documented abuses. "U.S. claims that they found no evidence of detainee abuse shows they weren't looking very hard," she said.
Yemen's war has left over 10,000 people dead, displaced millions, and pushed the already poor country to the edge of famine .
After Houthi rebels forced out the government of President Abed Rabbo Mansour Hadi, he fled to Riyadh, where the Saudi government kept him for more than a year. He was only allowed to return to Yemen Thursday at the beginning of an offensive led by the UAE to take control of the major port city of Hodeida, the key entry point for humanitarian aid.
The UAE's control over southern Yemen, and the prisons, has left many Yemenis worried that innocent civilians are being pushed into the arms of the very extremists that Emirati forces claim they are fighting.
"In the prisons, they are committing the most brutal crimes," said a Yemeni commander currently in Riyadh. "Joining ISIS and al-Qaida became a way to take revenge for all the sexual abuses and sodomization. From here, the prisons, they are manufacturing ISIS."
He spoke on condition of anonymity to avoid retaliation from the Emiratis.
One middle-aged man said he has been in prison since 2016, and has been moved across the network of secret prisons multiple times. He said he was interrogated 21 times, during which he was tortured with electricity, beatings, and attack dogs while he was blindfolded and chained.
"They beat me up with electric wires, with steel, an electric shock, or they take off the clothes except for the underwear and stomp on my body and face with their boots. The soldiers would carry you up in the air and dump you on the ground."
The AP previously confirmed 18 detention sites, but he named 21, including 13 prisons and 8 military camps.
Another prisoner gave the AP what he said were the real names of five Emirati torturers. UAE officials did not respond to requests for comment about the men.
One of the most brutal torturers is Yemeni, a former prisoner called Awad al-Wahsh, who was detained and tortured before agreeing to work with the Emiratis, four witnesses told the AP. His supervisor, Yosran al-Maqtari, could not be reached for comment. Al-Maqtari is Aden's chief of anti-terrorism.
Other torturers named by detainees are Emirati officers known to prisoners by their noms de guerre: Abu Udai, Abu Ismail, and Hitler.
The prisoners who were sexually abused in March had tried to fight back. They had organized three hunger strikes to protest their treatment. They had launched a campaign with their families to get human rights groups to secure their release.
That's when the 15 Emirati officers showed up with their dogs.
