The US military killed a senior ISIS leader in a raid in Syria on Friday, as well as two of his ISIS-affiliated sons, according to a release from US Central Command.

The military gave few details on the ground operation, but counterterrorism raids have typically involved helicopter-borne Special Operations commandos.

Dhiya’ Zawba Muslih al-Hardani, who was identified as the ISIS leader, was killed in the operation along with his sons Abdallah Dhiya al-Hardani and Abd al-Rahman Dhiya Zawba al-Hardani, according to U.S. Central Command, or CENTCOM.
