Rioting in Northen Nigeria, houses burnt, property destory, churches burnt down after INEC declares Goodluck Jonathan as the winner of 2011 election
Earlier, rioting erupted in several towns in Nigeria's predominantly Muslim north amid allegations of vote-rigging and results showing sharp divisions between the north and the south.

Protesting youths challenged soldiers deployed to the streets of Nigeria's second-largest city of Kano, and troops sought to push them back, an AFP correspondent said.

Several incidents of violence have been reported, including a church being burned down in the state of Kaduna.

Protesters stopped cars and demanded that passengers express support for Buhari, whose stronghold is in the north.

A police spokesman said security had been deployed to the city of Sokoto to contain youths burning bonfires in protest over the vote.

"Their grievance is this: that this election has been rigged," they don't believe the results that have been announced by the country's Independent National Electoral Commission."

Buhari, of the Congress for Progressive Change (CPC), told reporter that the poll had been systemically rigged.

"We have evidence in our hands that the computers [used in the voting process], were programmed to produce rigged results.”
