"Centcom is doing what they normally do, which is assessing the credibility of those allegations right now," Davis said on Monday.
"What I told you Friday, that was based upon initial battle damage assessment…That initial assessment was zero…We are now going to go back and do this credibility assessment."
On Thursday, the Syrian Observatory for Human Rights reported 42 people, mainly civilians, were killed when an airstrike hit a mosque in the al-Jinah village southwest of Atareb in the western countryside of Aleppo.
Davis said Friday that the US strike targeted a building adjacent to the mosque. He noted, however, that the he did not know what building’s association with the mosque was.
