Unions in Nigeria organised a general strike on 16 November after the government failed to cut petrol prices.
Workers were protesting at a 23% rise in petrol, diesel and kerosene prices in September. Unions said a government concession to cut kerosene prices was insufficient. A Nigerian court ruled against the strike but unions ignored the ruling.
A four-day nationwide strike in October shut down banks, businesses, shops and public services.
Unions targeted crude oil production and exports as part of the stoppage. Nigeria is the world’s seventh-largest oil producer and the strike disrupted the oil industry, which exports more than two million barrels a day.
