Burundian soldiers clashed with unknown militants who had entered Kayanza province from neighboring Rwanda, according to the BBC.

One militant was captured, two others were injured and have been taken to a local health center.

The crisis in Burundi revolves around President Pierre Nkurunziza's bid to stand for a third straight five-year term, which his opponents say is unconstitutional and violates a peace deal that ended a dozen years of civil war in 2006.

Over 70 people have been killed in more than two months of protests, with over 158,000 refugees fleeing to neighboring countries, according to the UN.
