US drones launched a massive attack against an al-Shabaab training camp 120 miles north of the Somali capital city of Mogadishu, according to the Pentagon. Spokesman Capt. Jeff Davis claims over 150 militants were slain in the attack.

Officials say that they were watching the camp “for several weeks” prior to the attack, and the Pentagon claimed they posed “an imminent threat to US forces.” It’s not clear where those US forces are that were at risk.

The attack reported took place on Saturday, and US officials are insisting that there are no indications of any civilian casualties. This is a common claim after US strikes, though time and again civilian tolls start cropping up in the days that follow.

The Australian government also reported having seized a shipload of weapons that were on a fishing boat near Oman, claiming that they believe the weapons were heading for Somalia. This is adding to talk that al-Shabaab is on the rise as a regional force.
