ISIS initiated the attack on the An Tanf garrison with a vehicle bomb and between 20 to 30 ISIS fighters followed with a ground assault and suicide vests, officials said.
Coalition and partnered forces defended against the ISIS attack with direct fire before destroying enemy assault vehicles and the remaining fighters with multiple coalition airstrikes, officials said.
In southern Syria, officials said, vetted Syrian opposition forces focus on conducting operations to clear ISIS from the Hamad Desert and have been instrumental in countering the ISIS threat in southern Syria and maintaining security along the Syria-Jordan border.
