According to Biden, the successful operation occured last night in the Middle East after his approval.

Biden promises to give more details on the development.

He writes:

Last night at my direction, U.S. military forces in the northwest Syria successfully undertook a counterterrorism operation to protect the American people and our Allies, and make the world a safer place. Thanks to the skill and bravery of our Armed Forces, we have taken off the battlefield Abu Ibrahim al-Hashimi al-Qurayshi—the leader of ISIS. All Americans have returned safely from the operation. I will deliver remarks to the American people later this morning. May God protect our troops.
