US Special Forces killed ISIS leader Abu Ibrahim al-Hashimi al-Qurayshi in a counterterrorism mission in northwest Syria Wednesday evening, President Joe Biden announced Thursday morning.

It was the the biggest US raid in the country since the 2019 operation that killed ISIS leader Abu Bakr al-Baghdadi.

Sources on the ground reported multiple fatalities. At least 13 people were killed in clashes that took place during and after the raid -- including six children and four women -- according to the Syrian civil defense group, the White Helmets. There were no US casualties, according to the Pentagon.

"Last night at my direction, US military forces in northwest Syria successfully undertook a counterterrorism operation to protect the American people and our Allies, and make the world a safer place," Biden said in a statement. "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."
