The Department of Defense continues to gather information on a coalition airstrike in Syria on Saturday night.

"While we are still trying to determine all the facts, if we mistakenly struck a Syrian military position we regret doing so, especially the loss of lives. " said Pentagon Spokesman Peter Cook.

"As Centcom previously disclosed, the coalition aircraft conducting the mission believed they were striking ISIL forces near Dayr Az Zawr. In addition, the coalition air operations center earlier in the day notified Russian officials that coalition aircraft would be operating in that area, and no concerns were voiced at that time." said the spokesman.

"We will review all aspects of this strike to determine what if any lessons should be learned. In the meantime, the coalition's effort will remain focused on delivering ISIL a lasting defeat." the spokesman added.
