Mr Ndayishimiye, 52, a retired army general, won last month’s presidential election as the ruling party’s candidate, defeating the opposition’s Agathon Rwasa and five others.
“I will defend Burundi’s sovereignty and ensure freedom of every Burundian citizen and protection,’’ Mr Ndayishimiye said at the ceremony in the political capital, Gitega. “What did those who went to complain to the world, get? I rather call on them to come back,’’ Mr Ndayishimiye said. The constitutional court ruled on Friday that Mr Ndayishimiye should be sworn in immediately, easing concern that powerful generals would dispute the succession.The court also dismissed challenges to the election result by the opposition, which alleged violence and intimidation. Mr Ndayishimiye was confirmed as the winner with 69 per cent of votes.
