Attackers kill 3 South Korean doctors in Nigeria

POTISKUM, Nigeria (AP) — Attackers in northeastern Nigeria killed three South Korean doctors, beheading one of the physicians, in the latest onslaught targeting 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.
