Protesters took to the streets in Burundi for a second day on Monday after activists said at least five people were killed in unrest on Sunday.
The protests were triggered by the president’s nomination that allows him to run for a third term, a move critics say violates the constitution.
Police broke up a march of around 1,000 youths, who were trying to reach the centre of Bujumbura.
Several other demonstrations were reported to be taking place in other areas, a day after at least two protestors were shot dead and several more wounded in clashes with police.
Protesters say President Pierre Nkurunziza broke the constitution and the Arusha peace agreement, which limits the president to two five-year terms, by saying on Saturday he would run again in the June 26 vote.
His supporters say his first term does not count as he was picked by lawmakers, not elected.
The number of those killed by Sunday was two however sources say at least 5 people have lost their lives in the running battles with anti riot police in Bujumbura.
The ruling CNDD-FDD party has repeatedly denied charges that its youth wing is armed and trying to cause violence. The head of police was expected to hold a news conference later in the day.
A Reuters witness said the army had been deployed on the streets and now outnumbered police.
Activists, who also reported the army deployment, said this could help calm the situation because the army was widely seen as a more neutral force.
