Targets: Islamic State fighters, training compounds, headquarters and command and control facilities, storage facilities, a finance center, supply trucks and armed vehicles in the vicinity of Raqqa, Dayr az Zawr, Al-Hasakah and Abu Kamal.
Add one more, the Khorasan Group.
In addition to hitting targets around Raqqa in Syria with help from five Arab allies, the U.S. undertook a solo mission to strike an al Qaeda offshoot called the Khorasan Group.
The Pentagon said the organization was actively plotting "imminent" attacks, including on the U.S. homeland.
The announcement of the second mission was contained at the bottom of the CENTCOM statement about Monday's military action:
"Separately, the United States has also taken action to disrupt the imminent attack plotting against the United States and Western interests conducted by a network of seasoned al-Qa'ida veterans - sometimes referred to as the Khorasan Group - who have established a safe haven in Syria to develop external attacks, construct and test improvised explosive devices and recruit Westerners to conduct operations. These strikes were undertaken only by U.S. assets. In total, U.S. Central Command conducted eight strikes against Khorasan Group targets west of Aleppo to include training camps, an explosives and munitions production facility, a communication building and command and control facilities."
The Pentagon said that the mission against Khorasan was not assisted by the other Sunni Arab nations.
Pentagon Press Secretary Rear Adm. John Kirby said the military believes it hit its intended targets, but the assessment is still being conducted.
Kirby said it's believed the Khorasan group was in the "end stages" of plotting attacks against the West.
