KANO, Nigeria (AP) - Hundreds of Nigerian soldiers have descended on a city in the country's north after youths there went on a deadly rampage.
    
Local government official Daniel Sheshere says a 24-hour curfew has been declared across Niger state following the violence in its capital, Minna.
    
On Wednesday, young people set the local electoral commission official on fire, killing a police inspector who was guarding the building.
    
And the state governor had to be evacuated from his home by helicopter after the residence came under attack.
    
Demonstrations over spiraling fuel prices and corruption have turned violent in cities across Nigeria this week after the government made a highly unpopular decision earlier this month to end a subsidy program that had kept fuel costs low.
