Is it Terrorist or Insurgent?

Confederate Yankee clarifies the terminology:

The reason that we've been reading more over the past few days
about attacks directed against al Qaeda—more than Sunni insurgents, more than
Shia militiamen—is that elements of al Qaeda have been specifically targeted by
U.S. and Iraqi forces in Operation Arrowhead Ripper in Diyala Province, in
Operation Commando Eagle southwest of Baghdad, Operation Marne Torch southeast
of Baghdad, and in other operations throughout the country.

Hopefully they'll throw in whatever Iranians are nearby for good measure!
