Nigeria: Election violence 'left more than 500 dead'

A Nigerian human rights group says more than 500 people died after presidential elections earlier this month. Rioting broke out when it emerged that Goodluck Jonathan, a southern Christian - had defeated a Muslim candidate from the mostly Islamic north. Correspondents say Nigeria is braced for possible further unrest over governorship elections on Tuesday (26 April) in most of Nigeria's 36 states.
