Afghanistan released 100 Taliban prisoners, claiming they were among 5,000 detainees to be freed under a deal with the U.S.
Troops who are already in the country may have their deployments extended so missions can continue.
An Afghan government official said the releases were delayed because more time was needed to review the list of prisoners.
The four-star commander of U.S. forces in Afghanistan made the stunning admission Tuesday.
Afghan President Ashraf Ghani issued a decree Wednesday promising to release 1,500 Taliban prisoners as a goodwill gesture.
Hundreds of troops are heading out of the country as previously planned, but they will not be replaced.
The U.S. has said its troop withdrawal from Afghanistan will be linked to the Taliban keeping their promises.
Washington, which has long rejected the court's jurisdiction and refuses to cooperate with it, condemned the decision.
The peace deal calls for a comprehensive nationwide cease-fire to be negotiated in the intra-Afghan talks.
Col. Sonny Leggett said in a tweet that the “defensive” strike was the first U.S. attack against the militants in 11 days.
