JOHANNESBURG - The U.S. military says it has carried out an airstrike in Somalia against al-Shabab extremists, killing two fighters.

The U.S. Africa Command statement says the strike was carried out on Tuesday about 46 kilometers (28 miles) northeast of the port city of Kismayo.



The U.S. has carried out 20 such strikes this year against the Somalia-based al-Shabab. The al-Qaida-linked group is the deadliest Islamic extremist organization in sub-Saharan Africa and it often targets Somalia's capital, Mogadishu, with deadly attacks.



The U.S. since late last year also has carried out a number of drone strikes against a small presence of fighters linked to the Islamic State organization in the northern part of the Horn of Africa nation.
