U.S.-led coalition forces have not carried out any air strikes in Syria for three days as of Monday, a lull that contrasts with the continued intensity of Russia's bombing campaign.
According to Pentagon data, the last coalition strike was a drone attack on October 22 that targeted an ISIS vehicle and a "mortar tube."
Russia, on the other hand, continues to maintain an intense tempo as it nears the end of its first month of bombing in Syria.
The Russian defense ministry said Monday it had hit 94 targets in just the past 24 hours.
U.S. defense officials say Russian sorties have no bearing on coalition actions in Syria, and insist the situation reflects greater discrimination and refinement in terms of which targets are struck.
"It's not because of Russia," said Captain Jeff Davis, a Pentagon spokesman.
