Eugene comments on suicide bombings at three churches Sunday in Nigeria:

Atrocity has, unsurprisingly, begun to lead to atrocity, though fortunately at this point at a smaller scale, and apparently just beginning (which suggests that it can more easily be stopped); the Christian Science Monitor reports:

Frustrated with the government’s inability to stop a string of such attacks in recent months, some Christians responded today with reprisals, killing at least 7 more people….

Until today, Christians living in the predominately-Muslim north have mostly resisted being provoked to violence, responding instead with calls on the government to suppress Boko Haram and reestablish security. Today’s retaliation from some Christians is raising concerns that a cycle of religious violence could start in Nigeria, Africa’s most populous nation.
