“Secondary school pupils in north-eastern Nigeria have killed a teacher after apparently accusing her of desecrating the Koran, police say.

The teacher, a Christian, was attacked after supervising an exam in Gombe city. It is not clear what she had done to anger the students.

The authorities, concerned that communal unrest could break out, have ordered all the city’s schools to shut.

Similar accusations sparked riots in neighbouring Bauchi State last year.

At least 15,000 people have been killed in religious, communal or political violence since the country returned to civilian rule in 1999.”
