The Pentagon says it killed 150 ISIS fighters in an airstrike in eastern Syria, while the U.S. federal government was shut down Saturday.
The airstrike unfolded in one of the last remaining pockets of ISIS control along the Euphrates River near the border between Syria and Iraq, according to a statement from U.S. Central Command, responsible for American forces in the Middle East.
F-18 fighter jets from the USS Theodore Roosevelt aircraft carrier launched the strike.
While ISIS has lost 98 percent of its territory, the remaining 2 percent held by the terror group includes an area around the Syrian city of Al-Shaafah, where the strike took place. Top U.S. military officials have said they believe the head of ISIS, Abu Bakr al-Baghdadi, is hiding in the area.
