The Saudi-led coalition said it launched an airstrike Sunday on a Houthi target in southwestern Yemen.
Yemen rebels, known as Houthis, said the coalition hit a detention center, killing 60 people.
The coalition said it hit a facility in Dhamar where drones and missiles were stored and “all precautionary measures were taken to protect civilians.”
A rebel spokesman told the Associated Press that 170 captured government fighters were housed in the center.
Local residents, however, told AP that family members who were critical of the Houthis were housed in the center.
More than five years of fighting between the Houthi rebels and the Saudi-led coalition helping the Yemeni government have led to the deaths of thousands of civilians who are already facing severe food shortages and a lack of quality medical care.
