WASHINGTON: A US airstrike using multiple drones and manned aircraft struck a training camp in Somalia on Saturday, killing more than 150 Al-Shabab fighters who were preparing to launch a large-scale attack, likely against African or US personnel, the Pentagon said Monday.

Navy Capt. Jeff Davis, a Pentagon spokesman, said the US had been watching the site, called Raso Camp, for several weeks. He said it appeared that the training was ending and the operational phase of a suspected attack was about to start.

The evening strike involved both missiles and bombs.
