Vice President Sambo's house attacked, one killed

Three gunmen have killed a man outside an uninhabited house belonging to Nigeria's Vice President Namaadi Sambo, Police authorities in Kaduna have said.

Kaduna state police spokesman, Abubakar Balteh, told The Associated Press that the assailants killed a shoe-shiner and injured two policemen who were guarding Vice President Namadi Sambo's house Monday. He said the house was under renovation.

Balteh said rioters had burned down the house during postelection violence that swept across northern Nigeria after April 2011 presidential polls.

Human Rights Watch says the violence left at least 680 people dead in Kaduna state alone. Fighting started after President Goodluck Jonathan, a Christian from southern Nigeria, was declared winner. Many in Nigeria's north thought a Muslim from the north should have become president.

Meanwhile, authorities say attacks targeting police in a major city of Nigeria's northwest left two dead Monday
