The Saudi-led coalition fighting the Iran-backed Houthi movement in Yemen attacked a funeral there after receiving incorrect information from Yemeni military figures that armed Houthi leaders were in the area, an investigative body set up by the coalition said Saturday.

The Saudi-led campaign in Yemen has come under severe criticism since the Oct. 8 airstrike on the funeral gathering in the Yemeni capital Sanaa, killing 140 people according to one U.N. estimate, and 82 according to the Houthis.

Mourners who died in the attack included some of Yemen's top political and security officials, potentially galvanizing powerful tribes to join the Houthis in opposing a Saudi-backed exiled government.
