At least two people have been killed in violent clashes in Burundi, a day after President Pierre Nkurunziza launched his bid for a third term in office, the BBC news reported.

Thousands defied a ban to take to the streets of the capital Bujumbura.

Police shot live ammunition in the air to disperse them.

President Nkurunziza was nominated to run by his governing CNDD-FDD party.

Opponents say it is unconstitutional and threatens a peace deal that ended the 12-year civil war in 2005.

More than 300,000 people died in the war.
