'More than 200 dead' in Nigeria post-poll unrest

"In the whole region, from reports reaching Civil Rights Congress, the death toll is over 200," Shehu Sani, head of the organisation, told AFP. The numbers were compiled through his organisation's staff and associates.

He added that more than 1,000 people had been arrested in the city of Kaduna alone, where a 24-hour curfew had earlier gone into effect.

The riots started as results showed President Goodluck Jonathan won Saturday's elections. He was declared the winner on Monday night over his northern rival, ex-military ruler Muhammadu Buhari.
