Nigeria's security forces have demolished the headquarters of a Shia sect, whose members were accused of killing a rival Muslim cleric.
The security forces destroyed a school, a clinic and the living quarters of the sect in the north-western Sokoto state.
Although no official explanation was given for the demolition, it is being suggested that it is part of a plan to expel the group from the city.
Shia leader Kasimu Rimin Tawaye and some 100 followers remain in detention.
Mr Tawaye and his supporters were arrested after street fighting between them and followers of a prominent Sunni cleric, who was shot dead three weeks ago.
The cleric, Umaru Danmaishiyya, well-known in Sokoto for his sermons against Shias, was shot in a mosque on 18 July and died the following day.
