The US has shot down a pro-Syrian regime armed drone that was attacking US-led coalition forces near At Tanf in Syria. In a briefing, US Army Col Ryan Dillon, Operation ‘Inherent Resolve’ spokesman, said the drone was ‘MQ-1 like’ and that it was shot down by a US aircraft after it fired upon coalition forces carrying out a patrol outside a de-confliction zone in southern Syria.
The drone had munitions and was seen as a threat, and ‘so it was shot down’.
The description suggests it could be a Shahed 129 unmanned combat aerial vehicle.
UPDATE: Various reportas stating that this was an shootdown by an F-15E Strike Eagle.
