In Nigeria, new religious clashes broke out on Sunday between armed Christian and Muslim groups; two days after a series of explosions in Jos killed 32 people and wounded 74. Many of the victims were doing last-minute Christmas shopping. Jos is the capital of Plateau State in Nigeria's volatile Middle Belt. Authorities there are trying to contain tensions with security forces patrolling the area. Plateau state governor said the attacks were aimed at sparking violence between Christians and Muslims that would interfere with preparations for April's presidential poll. Current president Goodluck Jonathan is trying to solidify national support before next month's ruling party primary. His candidacy is made controversial by an unwritten north-south power-sharing agreement in the country's ruling PDP party that says the presidency should go to a northerner this term. Mr. Jonathan is from the south and only became president after the death earlier this year of President Umaru Yar'Adua, a northern Muslim for whom Mr. Jonathan served as vice president.
