Nkurunziza could not run for a third term in office but the country's constitutional court agreed with Nkurunziza (although some of its members had fled the country at the time of its vote). An attempted coup d'état on 13 May failed to depose Nkurunziza. He returned to Burundi, began purging his government, and arrested several of the coup leaders. Following the attempted coup, protests however continued and over 100,000 people had fled the country by 20 May causing a humanitarian emergency. There are reports of continued and widespread abuses of human rights, including unlawful killings, torture, disappearances, and restrictions on freedom of expression. Despite calls by the United Nations, the African Union, the United States, France, South Africa, Belgium, and various other governments, the ruling party held parliamentary elections on 29 June, but these were boycotted by the opposition. On 30 September 2016, the United Nations Human Rights Council established the Commission of Inquiry on Burundi through resolution 33/24.

However, much to the surprise of most observers, Nkurunziza later announced that he did not intend to serve another term, paving the way for a new president to be elected in the 2020 general election. On 20 May 2020, Evariste Ndayishimiye, a candidate who was hand-picked as Nkurunziza's successor by the CNDD-FDD, won the election with 71.45% of the vote.
