There were no lapses in judgment or decision-making in the Yemen raid that killed a Navy Seal, the top US commander for the Middle East said on Thursday.

Announcing he had completed an exhaustive review of the raid, Gen Joseph Votel also told the Senate armed services committee that a separate investigation found that between four and 12 innocent civilians had been killed during the January raid.

Votel said he saw no need for additional investigations.

During the raid, chief special warfare officer William “Ryan” Owens was killed, six other American service members were injured and a helicopter was lost.

Votel said the US gained valuable information on al-Qaida militants.
