Challenger Muhammadu Buhari won Nigeria's presidential election by 2.57 million votes, official results showed Wednesday, defeating incumbent Goodluck Jonathan in the first democratic change of power in Africa's most populous nation.
      

Nigerians on March 30 awaited the first results of a closely fought general election pitting President Goodluck Jonathan against ex-military ruler Muhammadu Buhari, as UN chief Ban Ki-moon called for calm after deadly riots followed 2011 polls.
      

Islamist group Boko Haram has vowed to make voting impossible in Nigeria's upcoming election after a spate of deadly attacks in the country's violence-wracked northeast.
      
The group's leader Abubakar Shekau said in a new video posted on Twitter late on Feb. 17 evening that his fighters would disrupt polling in Africa's most populous nation scheduled for March 28.

Nigeria has postponed its presidential election on security grounds as the Boko Haram conflict intensifies, handing a potential lifeline to the ruling party as it battles a tough challenge from the opposition.
