(http://news.bbcimg.co.uk/media/images/80860000/jpg/_80860666_line976.jpg) 'Free and fair' A regional coalition formed recently to fight Boko Haram was gaining the upper hand, Mr Moro said.
"I think that we don't have any reason not to be optimistic that they [the Nigerian military] are capable to bring the war to a level that will allow for a free and fair election," he said.
"I think that they know what stakes are involved - it's a national election, it's a national concern and the international community is watching."
Mr Buhari cautioned against any retaliatory acts of violence.
He said they could "only complicate the security challenges in the country".
A close race is being predicted between Mr Buhari, a former military ruler, Mr Jonathan.
