At least one person has been killed in Nigeria when a demonstration against the government's decision to end a fuel subsidy program turned violent. Furious protesters set tires on fire on a major expressway in Lagos on Tuesday and vandalized at least three gas stations. The protesters allegedly assaulted a soldier too. One protester was killed in the central city of Ilorin when police fired tear gas at the people protesting. The subsidy program had kept fuel costs down for more than two decades. The Nigerian government's announcement has led to a spike in petrol prices. A gallon of petrol cost about $3.5 dollars (94 cents per liter) on Tuesday - just over double Sunday's price of about $1.70 (45 cents per liter). The government says it will use $8 billion in savings to make much-needed infrastructure improvements. On Monday, Nigeria's President Goodluck Jonathan said he had formed a committee to ensure that the savings from the subsidy's end would be invested effectively to improve the quality of life of the people. Most Nigerians subsist on just $2 a day. There are fears now that the rising fuel prices will force food prices into a spiral as well.
