Nigeria, Africa's largest oil producer, ended oil subsidies on New Year's Day that had kept gasoline prices artificially low.
The cost of a liter of gasoline shot up from 65 naira (40 cents) to at least 141 naira (86 cents) virtually overnight.
Furious Nigerians have since taken to the streets, staging 'Occupy Nigeria' protests and mass demonstrations across the country.
Police have responded forcefully with many arrests. At least one person has died amid the unrest: 23-year-old student Muyideen Mustafa was allegedly hit by a police bullet in Ilorin, Kwara State, on January 03.
A police spokesman in Kano State also confirmed to CNN that they fired teargas into a crowd staging a midnight protest last weeka in order to disperse a largely peaceful demonstration by Muslims and Christians.
