"This strike was conducted within the parameters of the proposal approved by the President in March 2017, which allows the U.S. Department of Defense to conduct lethal action against al-Shabaab within a geographically-defined area of active hostilities in support of partner forces in Somalia," the statement said. "We will continue to assess the results of the operation and will provide additional information as appropriate."
A U.S. Africa Command spokesperson later said that unmanned drones were used for the strikes, both of which were conducted near the Banadir region.
The president gave the U.S. military authority to target al-Shabab in a designated area of Somalia south of Mogadishu with prior notification to the Somali government.
This authorization for offensive actions has been used sparingly. The first airstrike occurred in June, with two others following in July, including one on July 31 that killed Ali Jabal, a senior al-Shabab leader who was alleged to have planned terror attacks in Mogadishu.
