The United Nations special envoy to Yemen has condemned a Saudi-UAE-led coalition attack on a prison run by Houthi rebels and called on the military alliance to investigate the deadly air raids.
Martin Griffith’s statement late on Sunday came as the International Committee of the Red Cross (ICRC) said more than 100 people were “presumed killed” in the bombing in Dhamar city in western Yemen.
Houthi officials said at least 60 people had died in the attack overnight on Sunday. Dozens more were wounded.
Griffiths called the incident a “tragedy”.
“The human cost of this war is unbearable,” he said. “We need it to stop … I hope the Coalition will launch an inquiry into this incident. Accountability needs to prevail.”
Rescue workers continued to pull the dead and wounded from the rubble at the site of the attack north of the city of Dhamar. Houthi officials quoted by Al Masirah TV said the facility, formerly a community college, housed about 170 prisoners of war.
The attack was the deadliest so far this year by the coalition, according to the Yemen Data Project, a database tracking the war. The coalition, which intervened in Yemen’s civil war in 2015, has faced international criticism for air raids that have hit schools, hospitals and wedding parties, killing thousands of Yemeni civilians.
Al Jazeera’s Mohammed al-Attab, reporting from Dhamar, said prison guards at the scene said they reconstructed the building, which had been destroyed by previous Saudi-led attacks, and turned it into a detention centre as “it has not been used by students” following the recurring raids.
The head of the Red Cross delegation in Yemen, Franz Rauchenstein, said witnessing the “massive damage, seeing the bodies lying among the rubble, was a real shock.”
“Anger and sadness were natural reactions,” he added.
Meanwhile, a spokesman for the Red Cross told Al Jazeera that ICRC’s team delivered medical supplies to the hospitals where some of the wounded were taken.
Jason Straziuso said the ICRC also had “a forensics professional on site who will be helping this week with dead body management.”
“It’s clear that this building was full of about 170 detainees,” he said. “Warring parties should not be targeting people who are not a part of the fight – in this case, the detainees.”
Nazem Saleh was among those held at the facility. “We were sleeping and around midnight, there were maybe three, or four, or six strikes,” he told The Associated Press news agency.
“They were targeting the jail, I really don’t know the strike numbers … We were 100 persons on the ground level and around 150 on the upper level,” he said while on a stretcher in a local hospital.
The Saudi-UAE-led coalition confirmed air raids on Dhamar, but said it had targeted a Houthi site storing drones and missiles.
The Western backed alliance said it had taken measures to protect civilians in Dhamar and the assault complied with international law.
But Houthi rebels rejected the coalition’s claims the community college was a weapons store.
Abu Kinan, a Houthi official in charge of war captives, told Al Jazeera that the prison is “subject to the ICRC’s inspection every now and then”.
“Accusations by Riyadh are baseless, especially as its [the facility’s] coordinates have been shared with the Red Cross,” he said.
Meanwhile, human rights activists have placed blame on the Houthis for housing detainees, many of them dissidents, in facilities deemed dangerous as they had come under attack in the past.
Baraa Shiban, from the UK-based human rights NGO Reprieve, told Al Jazeera: “There is a crime committed by the Houthis in detaining political activists, journalists, and political dissidents – whom they used to put in places that they constantly have been advised by human rights NGOs not to put them in dangerous areas.
“Also, most of those people who died … haven’t even seen courts,” Shiban noted.
Human Rights Watch has also accused the Houthis of torturing prisoners, many of whom were subject to arbitrary arrest and enforced disappearances.
In a September 2018 report. the New York-based watchdog said it documented 16 cases of illegal imprisonment by the Houthi rebels.
It said former detainees described being beaten with iron rods, wooden sticks, and assault rifles, and said conditions in Houthi custody included poor hygiene, limited access to toilets, and lack of food and healthcare.
The Saudi-led coalition intervened in Yemen in March 2015 against the Houthis after they swept the internationally-recognised government of President Abd-Rabbu Mansour Hadi from power in the capital, Sanaa, and most of the north.
With logistical support from the United States, the Saudi-UAE coalition has carried out more than 18,000 raids on Houthi-held areas in an attempt to reverse their gains.
In recent months, the rebel group has stepped up cross-border missile and drone attacks on Saudi Arabia.
The air raids in Dhamar come after the coalition has been distracted in recent weeks by a battle for control of the south, which has pitted Hadi’s Saudi-backed forces and southern separatists who have been trained and equipped by the UAE against each other.
The war in Yemen, currently in its fifth year, has already killed tens of thousands of lives and sparked what the United Nations calls the world’s worst humanitarian crisis.
