Three people were killed in Burundi just hours before the arrival of United Nations Secretary General Ban Ki-moon on Monday.
The three were killed in gun and grenade attacks in the East African country on Sunday, ahead of Ban’s visit.
The UN secretary general is seeking to end the bloodshed over President Pierre Nkurunziza’s disputed re-election.
The UN is under growing pressure to show it can halt the violence, two decades after the 1994 genocide of ethnic Tutsis and moderate Hutus by the Hutu majority in neighboring Rwanda, which has a similar ethnic make-up as Burundi.
Burundi descended into chaos in April 2015 after President Nkurunziza declared that he would run for a controversial third term in office, going on to win the elections held in July.
More than 400 people have been killed in the chaos with thousands fleeing to neighboring countries.
Ban is due to meet Nkurunziza on Tuesday after arriving late on Monday. It is not immediately clear what plan Ban will bring to stem the violence, if any.
