Bujumbura - At least one person was killed and three wounded in Burundi on Thursday in a fresh outbreak of clashes between demonstrators and police, witnesses said.
A small group of protesters clashed with government supporters, thought to be members of the ruling party's militia, in the Kinama district of the capital Bujumbura.
Police opened fire on the demonstrators, killing one with a bullet to the head and wounding three others, AFP reporters witnessed.
Tensions remained high in the area, with protesters arming themselves with sticks and batons.
Over a dozen people have been killed and scores wounded since late April, when the ruling CNDD-FDD nominated President Pierre Nkurunziza to stand for reelection, triggering daily protests.
Opposition parties and civil society groups say Nkurunziza's third-term quest violates both the constitution, which limits a president to two terms in office, and the accords that ended a 13-year civil war between Tutsis and Hutus in 2006.
On Wednesday Nkurunziza insisted he would run for a third term, defying international pressure.
