Muslim pupils at a secondary school in northeastern Nigeria beat a Christian teacher to death after accusing her of desecrating the Koran

Ardo Hazzad:

Oluwatoyin Olusase, a Christian, was invigilating an Islamic Religious Knowledge exam at the school in Gombe state when the incident occurred. The students attacked her outside the school compound after the exam and killed her, witnesses said.

It was not clear exactly what Olusase had done that angered the students.

Police confirmed the killing and said their intervention had prevented the incident from turning into a riot.

"We have received information that a female teacher has been lynched by her students. We are investigating the report," Gombe state police commissioner Joseph Ibi said.

At least five people were killed and several churches burned down in February 2006 in the neighbouring state of Bauchi by Muslims infuriated that a Christian teacher in a secondary school had tried to confiscate a Koran from a student who was reading it during class.

Word got out into the streets that the teacher had desecrated the Koran, infuriating Muslims who went on the rampage.

At least 15,000 people have died in religious, communal and political violence in Africa's most populous country since 1999, when Nigeria returned to democracy after 30 years of almost unbroken military rule.

The Religion of Peace claims another victim.
