http://www.bbc.co.uk/news/world-africa-13123280Incumbent Mr Jonathan has emerged as a clear winner in the presidential poll, with the electoral commission saying he received about 57% of the votes cast.
Rioting spread across the Muslim north - the opposition's powerbase - as the outcome became clear.
It is the first time in Nigeria's recent history that the election result has exposed the huge division between the Muslim north and Christian south.
Incumbent Goodluck Jonathan has won in nearly all southern states, which are predominantly Christian except for one, while his main challenger Muhammadu Buhari won in the Muslim north-east and north-west. Both candidates shared votes in the north central area which has a substantial Muslim and Christian population.
