Physicians have also been implicated in ideologically driven mass casualty attacks, but more as planners (Ayman al-Zawahiri, Madrid-bombing planner Abu Hafiza) or political thinkers (Franz Fanon) and not in placing themselves in harm's way.
Police said they prevented the bombing in a train station in Madrid last Christmas Eve, arresting the alleged plotters and seizing those who were planning to carry out the attack hours before it was to have taken place, Acebes said.
