The United States conducted an air strike targeting a senior leader of the al-Shabab terrorist group in Somalia, the US defence department said.
According to the BBC, the US has supported the African Union (AU) force that has driven al-Shabab out of the capital Mogadishu and other towns since 2011.
The leader of the insurgent group, Ahmed Abdi Godane, was killed in September during a US air strike.
A statement by the US defence department said that it would provide further details after assessing the results of the operation.
The air strike was carried out just two days after top al-Shabab militant, Zakariya Ahmed Ismail Hersi, surrendered to the Somali police.
