Two church terror attacks in Nigeria JOS, Nigeria, June 10 (UPI) -- At least five people were reported dead in two separate attacks on Christian churches in Nigeria Sunday, witnesses said. The fatalities were reported in the city of Jos, where a suicide bomber apparently drove a car packed with explosives into the Christ Chosen Church of God and leveled the building during Sunday services. The second attack was reported in the northern city of Biu, Voice of America said. No one claimed responsibility for the attacks, although the radical Muslim terrorist group Boko Haram has taken credit for similar attacks in the past. Previous church attacks in Nigeria resulted in a declaration of a state of emergency in several northern states; however there have been no apparent major breakthroughs in the campaign against the militant Islamic group. The government's apparent lack of effectiveness stirred up public anger in the aftermath of the Jose attack. CNN said onlookers actually drove police away from the church and set up checkpoints in the area. Some witnesses angrily asked how the car made it through government checkpoints in the area and drove past several other churches without interference before plowing into Christ Chosen.
