A recent attack on US military personnel in eastern Syria, which caused four to suffer traumatic brain injury, was intentional and not "indirect fire", the Pentagon said on Monday.
Pentagon spokesman John Kirby said at least one person had deliberately placed explosives near US troops.
There is "concern about some sort of insider threat" if it is now assumed that the attack was carried out through deliberately placed explosives, Mr Kirby said.
US Central Command earlier said the attack could have been indirect fire -- a military term that usually means a rocket attack or shelling -- but last week determined that the explosives had been planted in an ammunition depot and shower block. The incident is still under investigation, Centcom said.
Mr Kirby and the US-led coalition have not indicated who was responsible for the attack.
It is unclear if the incident was caught on video surveillance and there were no details of the number of people involved.
US troops were posted to Syria during the campaign against ISIS, in partnership with a Kurdish-led group called the Syrian Democratic Forces.
Iran-backed militias have established a foothold in Syria while fighting in support of President Bashar Al Assad during the country’s 11-year war.
While Iranian-backed forces have occasionally attacked US troops in Syria with rockets, ISIS militants could also be responsible for placing the explosives.
It raises the question of how secure the base is against the threat of insider attacks.
All four US personnel who were injured in the attack have resumed service or will soon return to duty and will be continually evaluated by medical personnel, Mr Kirby said.

Top tips
Create and maintain a strong bond between yourself and your child, through sensitivity, responsiveness, touch, talk and play. “The bond you have with your kids is the blueprint for the relationships they will have later on in life,” says Dr Sarah Rasmi, a psychologist.
Set a good example. Practise what you preach, so if you want to raise kind children, they need to see you being kind and hear you explaining to them what kindness is. So, “narrate your behaviour”.
Praise the positive rather than focusing on the negative. Catch them when they’re being good and acknowledge it.
Show empathy towards your child’s needs as well as your own. Take care of yourself so that you can be calm, loving and respectful, rather than angry and frustrated.
Be open to communication, goal-setting and problem-solving, says Dr Thoraiya Kanafani. “It is important to recognise that there is a fine line between positive parenting and becoming parents who overanalyse their children and provide more emotional context than what is in the child’s emotional development to understand.”
