It's a sign of growing U.S. anti-terrorism efforts in the region. Earlier in October, the U.S. Navy SEALS conducted a raid in Somali to take down a Kenyan al-Shabab member.
After the Iraq and Afghanistan wars, the U.S. is evolving the way it fights terrorism. Instead of boots on the ground, targeted drone strikes are becoming the preferred method.
However, Dr. James Dorsey, senior fellow at the S. Rajaratnam School of International Studies, says although the U.S. prefers drone strikes because they're "cleaner" than boots on the ground, the drones present several problems.
"The problem with the drone strikes is that at times civilians or people not associated with the targets are among the casualties. The second thing is it really doesn't take into account what the facts on the ground are, what tribal relationships are. So often what these strikes do is they do take out a target...but at the same time, they could aggravate tensions on the ground, and have long-term consequences.
