There were several new outbreaks of interfaith violence around the world this week. In Nigeria, at least 10 people died in an attack on a church and a nearby market, the latest in a long series of attacks by Islamist extremists who often target Christians. In Tanzania, at least two people were killed and dozens injured in a bombing during the dedication of a new Catholic church. And in Bangladesh, at least 22 died in clashes between police and Muslims who were rallying in support of anti-blasphemy laws.
