Washington (CNN) The US military conducted an airstrike Sunday that killed Abdulhakim Dhuqub, a high ranking ISIS-Somalia official.

US Africa Command, which oversees US military operations on the continent, said in a statement Monday that the strike targeted a vehicle near Xiriiro, Bari Region.

The statement refers to Dhuqub as the terror affiliate's "second in command," saying he "was responsible for the daily operations of the extremist group, attack planning, and resource procurement."

ISIS' Somalia branch is a relatively small affiliate of the terror group, commanding fewer than 150 fighters according to US defense officials. It is much smaller than the al Qaeda affiliated Al-Shabaab militant group which commands more than 5,000.
