U.S. forces struck the al-Shabaab terrorist group in Somalia on Sunday, according to U.S. Africa Command.

It was the most recent attack since President Trump delegated more authority to commanders on the ground. AFRICOM did not immediately report casualties, intended targets or the precise location of the strike around 7:30 a.m.

"We are currently assessing the results of the operation, and will provide additional information as appropriate," Patrick Barnes, an AFRICOM spokesman, said in a released statement.

The Islamic extremist al-Shabaab group is aligned with al Qaeda and has been fighting and carrying out terrorist attacks in eastern Africa for years.

Barnes said the operation was aimed at "defeating al-Shabaab and establishing a safe and secure environment in Somalia."

In April, Trump allowed AFRICOM more authority to carry out operations and strikes against the group. The president has also given Defense Secretary Jim Mattis and military commanders under him greater autonomy over anti-terrorism operations in Iraq, Syria and Afghanistan.

AFRICOM killed an estimated eight al-Shabaab militants in June during an airstrike on a group command and logistics post about 185 miles southwest of Somalia's capital of Mogadishu.
