This is simply horrific:

Assailants in northeastern Nigeria killed three North Korean doctors, beheading one of the physicians, in the latest attack on health workers in a nation under assault by a radical Islamic sect, officials said Sunday.

The deaths Saturday night of the doctors in Potiskum, a town in Yobe state long under attack by the sect known as Boko Haram, comes after gunmen killed at least nine women administering polio vaccines in Kano, the major city of Nigeria’s predominantly Muslim north.

Boko Haram, whose name means “Western education is sacrilege,” has been attacking government buildings and security forces over the last year and a half. In 2012 alone, the group was blamed for killing at least 792 people, according to an AP count.

I wonder if these guys even knew who they were attacking. I also wonder if the North Koreans will handle this the way their Soviet comrades used to handle this sort of thing.
