Live reaction to Buhari victory
Gen Buhari, of the All Progressives Congress (APC), has become the first opposition candidate to win a presidential election in Nigeria.
In a televised speech, he said: “In tackling the insurgency, we have a tough and urgent job to do. Boko Haram will soon know the strength of our collective will. We should spare no effort until we defeat terrorism.”
Much of Gen Buhari’s support was in the north, in particular the north-east, which has suffered from Boko Haram’s six-year insurgency. The militants have killed thousands of people in their drive to establish an Islamic state.
Many people accused Mr Jonathan of not taking Boko Haram seriously and thought Gen Buhari would be better positioned to defeat the militants.
