Nigeria's Christians are asking American churches to pray they'll be safe from attacks this Christmas.
Dozens of Christians there died in bombing attacks during Christmas services the past two years.
Rev. Musa Asake, the general secretary of the Christian Association of Nigeria, said he's "very, very worried."
The radical Islamic group Boko Haram is carrying out a war to drive Christians from Northern Nigeria.
More than 770 people have been killed in Boko Haram attacks so far this year, according to an Associated Press count, making 2012 the worst year of violence attributed to the group.
But Asake said that won't stop Nigerian Christians from going to church on Christmas. He's asking believers in America to pray that, "the Lord will intervene to protect churches."
