SANAA, Yemen, Sept 2, (AP): Yemeni medics said on Monday they pulled dozens of bodies from the rubble of a Houthi rebelrun detention center that was hit a day earlier by Saudi-led coalition airstrikes, killing over 100 people and wounding dozens.

It was the deadliest such attack so far this year in a stalemated four-year war that’s claimed tens of thousands of lives, thrust millions to the brink of famine and spawned the world’s worst humanitarian crisis.

The Saudi-led coalition, which has fought the Iranbacked Houthis since 2015, has faced international criticism for airstrikes that have hit schools, hospitals and wedding parties, killing thousands of civilians. He said the Red Cross never told the coalition that there were detainees at the site, which he said was not on a UN coordinated no-strike list.

The UN provides the coalition with coordinates for locations such as hospitals, schools and official prisons to ensure they are not hit by airstrikes. “The only known prion (in the area) is located 10 km (6 miles) north of the targeted site,” he said.
