The U.S. has described the dry and rugged mountains of northern Somalia as the main hub from which ISIS controls its global operations. Amid an increasing number of U.S. drone strikes and raids supporting the Somali government in the war against ISIS, the United States is now expanding its presence in the port city of Bosaso and effectively building a new military base, which will be used for combat and surveillance operations targeting “terror groups” in the region as well enhancing maritime security, according to Somali security officials in Puntland. The CIA will also expand its operations there, the officials said.
