US airstrike in Somalia kills 'over 150 al-Shabab militants'

A US airstrike on a training camp in Somalia run by al-Qaeda linked al-Shabab militants over the weekend killed more than 150 fighters who were planning a "large-scale" attack, the Pentagon said Monday.

Pentagon spokesman Captain Jeff Davis said the strike occurred sometime Saturday on a camp called Raso, about 120 miles (195 kilometers) north of Mogadishu. Manned warplanes and drones were used in the attack.

"The fighters were there training and were training for a large-scale attack. We know they were going to be departing the camp and they posed an imminent threat to US and (African Union) forces," Pentagon spokesman Captain Jeff Davis said.

"Initial assessments are that more than 150 terrorist fighters were eliminated," he added.

Davis said the group had neared the completion of specialist training to conduct "offensive operations," but he did not give any details about the assault the fighters were allegedly planning.

"Their removal will degrade al-Shabab's ability to meet the group's objectives in Somalia, which includes recruiting new members, establishing bases and planning attacks on US and AMISON (African Union Mission to Somalia) forces there," he said.

The training camp had been under surveillance for some time ahead of the strike.

"There was a sense that the operational phase was about to happen," Davis said.

Al-Qaeda-aligned al-Shabab militants have claimed responsibility for a string of recent attacks including a twin bombing at a busy restaurant in the Somali city of Baidoa last month.
