Rights group Amnesty says it has found five possible mass graves near Burundi's capital, where security forces are accused of killing scores of people in December.

Meanwhile, authorities have released two foreign journalists arrested on Thursday in the capital Bujumbura.

Violence in the country began last April, when President Pierre Nkurunziza announced he would seek a third term.

At least 439 people have died and 240,000 have fled abroad, the UN says.

African Union (AU) leaders are due to discuss the crisis in Burundi at a summit in Ethiopia.

They want Mr Nkurunziza to accept peacekeeping troops to prevent Burundi sliding into ethnic conflict, but analysts say he is unlikely to agree.
