A U.S. airstrike killed 13 Islamic State fighters in Somalia's semiautonomous Puntland region on Wednesday, the U.S. military said, days after another strike killed three.
The U.S. military has stepped up its campaign of airstrikes in Somalia since U.S. President Donald Trump took office, saying it has killed more than 800 militants in two years.
Islamic State, also known as ISIS, has gathered recruits in Puntland, although experts say the scale of its force is unclear and it remains a small player compared to al-Qaida-linked al-Shabab group that once controlled much of Somalia.
U.S. Africa Command (AFRICOM) said late on Thursday the latest strike targeted an ISIS-Somalia camp in Golis Mountains.
"At this time, it is assessed the airstrike on May 8 killed 13 terrorists," it said.
AFRICOM said in April it had killed Abdulhakim Dhuqub, identifying him as Islamic State's deputy leader in Somalia.
Somalia has been mired in civil war and an Islamist insurgency since 1991 when clan warlords overthrew a dictator and then turned on each other.
Al-Shabab was pushed out of the capital Mogadishu in 2011 but retains a strong presence in parts of southern and central Somalia and has often clashed with Islamic State.
