US forces conducted a raid against ISIS terrorists in northwest Syria on Sunday, a US official said, according to ABC News.
Three were killed in the operation, and the US is assessing their identities. There were no US casualties, according to the official.
“The raid resulted in the probable death of a senior ISIS Syria leader and operational planner responsible for planning terror attacks in the Middle East and Europe,” US Central Command (CENTCOM) spokesman Joe Buccino told ABC News in a statement.
Earlier this month, US forces killed an ISIS senior leader in a strike in northwest Syria. The leader was identified as Khalid ‘Aydd Ahmad Al-Jabouri, who the US army said was responsible for planning attacks in Europe and Turkey, and developing ISIS’s leadership network.
In February, an ISIS group leader was killed and four US troops wounded in a US helicopter raid on northeast Syria.
A month earlier, American forces captured two ISIS members during an air and ground assault in eastern Syria.
ISIS overran large swathes of Syria and neighboring Iraq in 2014, proclaiming a “caliphate” in land it controlled.

Several military offensives, including those backed by the US-led international coalition, have since seen ISIS lose most areas it once controlled, including the loss of their de facto capital in Raqqa, Syria.
However, ISIS sleeper calls remain in the area continue to carry out deadly attacks in Syria and Iraq. The US has roughly 900 troops in Syria as part of its effort to defeat ISIS in the region.
