A Yemeni medical source has recovered 123 bodies of victims of the Saudi-Emirati coalition bombing at the end of August on a Houthi-run prison in the central province of Dhamar.
An official at the Houthi health ministry said the search for remains or bodies was still going on in the rubble of the 170-strong detention center.
UN officials have condemned the bombing of the Saudi-Emirati alliance for jail, while the Red Cross refuted the alliance's allegations that it targeted a weapons store belonging to the Houthi group.
The UN envoy to Yemen, Martin Griffiths, condemned the coalition airstrikes that killed dozens of prisoners and detainees loyal to the legitimate government and wounded others.
"The raids are a tragedy that has made the human cost of the war in Yemen unbearable and must stop," Griffiths said in a joint statement with UN humanitarian coordinator for Yemen Liz Grande.
Griffiths called on the Saudi-UAE coalition to investigate the raids on Dhamar and activate accountability, stressing that the only way to end the killings and suffering in Yemen is to end the conflict.
A spokesman for the Saudi-Emirati coalition, Turki al-Maliki, said the shelling hit what he called a "legitimate target" and that the coalition had taken measures to neutralize civilians during the operation.
The coalition talked about targeting a storehouse of drones and missiles, while Houthi media broadcast yesterday horrific pictures showing torn bodies and others stuck in the rubble at the site of the coalition bombed and suffered great destruction.
