(AP Photo/IntelCenter) (Newser) – The American militant arrested in Pakistan yesterday is not Adam Gadahn, as previously reported by Pakistani intelligence officials. "Our initial impression was that the guy was Gadahn but that information now looks incorrect," an official told Reuters. Both the al-Qaeda spokesman and the detained American have been known to use some form of the alias Abu Yahya. "Probably the name and his origin caused the confusion," the official said.
