Nigeria’s electoral commission (INEC) has described the burning down of one of its offices in Plateau state as an “emerging trend”.
Nigerians go to the polls on Saturday to elect the next president.
In a statement INEC says that the weekend’s incident was the second this month and calls on the police to provide extra security.
The police are investigating the cause of the fire, but these incidents happen every electoral cycle, says BBC Pidgin editor Adejuwon Soyinka.
Inec says that in the weekend’s fire nearly 6,000 voters’ cards were destroyed along with other election materials.
