Burundi: The chronology of a crisis

July 21, 2015: After three months of protests against Pierre Nkurunziza's third term and fierce battles between Nkurunziza’s supporters and the opposition, the presidential election was finally held. But the opposition chose to boycott it.

July 24, 2015: President Nkurunziza wins the presidential election in the first round. With 69% of the vote, he was far ahead of his main challenger, Agathon Rwasa. By the end of July, Rwasa was surprisingly elected as first vice president of the national assembly, sparking criticism from his former allies.

August 1, 2015: Adolphe Nshimirimana, head of internal security and considered the right-hand man of the president, is assassinated. In a statement, the European Union raised concern over this "dangerous escalation of violence." Brussels calls for "restraint" and a resumption of "dialogue."

August 3, 2015: Pierre-Claver Mbonimpa, head of the human rights organization (APRODH), survives an assassination attempt and is evacuated to Brussels for medical treatment. But his family continues to be targeted and in October 2015 one of his sons-in-laws is killed and a month later his son is also murdered in Bujumbura.

Since the crisis began, a large number of Burundian refugees fled to neighboring Rwanda. On November 6, 2015, President Kagame spoke about what was happening in Burundi: "People are dying every day, corpses littering the streets," he said. "They should learn from what happened here." Nkurunziza’s team fired back, accusing Rwanda of training rebels seeking to destabilize the country.

December 12, 2015: A crackdown begins on neighborhoods like Nyakabiga that were believed to be strongholds of protesters. This came after an attack by rebels against three military camps. More than a hundred victims were identified. The UN said that 400 people had been killed since April 26 and 3,500 were arrested in connection with the crisis.

December 17, 2015: The United Nations warns that the situation in Burundi is "highly explosive" and that the country is on the path to a civil war. Adama Dieng, the UN special rapporteur on the prevention of genocide, warns of a possible genocide. "If a conflict breaks out on a large scale, we cannot pretend that we did not know about it," he said.

December 23, 2015: A former army officer in the Burundian army forms the "Republican Forces of Burundi" (FOREBU). Lieutenant Colonel Edouard Nshimirimana accuses Pierre Nkurunziza of instigating the security forces to commit acts of violence and pitting police and military against each other along ethnic lines.

December 28, 2015: Inter-Burundian peace talks start in Entebbe under the auscipices of Ugandan President Yoweri Museveni. The African Union (AU) also announces that it will deploy a 5,000-strong peacekeeping force to help secure the country, an idea that is immediately rejected by the Burundian government.

January 2016: Mediation fails to kickoff in Arusha. A month later, February 25 -26, the African Union sends a "high- level" delegation to Bujumbura led by South African President Jacob Zuma. It’s another failed attempt. Bujumbura refuses to talk with the opposition CNARED. UNHCR announces a group of independent experts to investigate violations of human rights in Burundi.

April 18, 2016: The UN Human Rights Commissioner Zeid Ra'ad Al Hussein criticizes Burundi’s security forces for routinely torturing prisoners. Since the beginning of the year, his team had registered at least 345 new cases of torture. He urged the Burundian authorities to immediately put an end to torture in all its forms.

May 21, 2016: After another delay, the Inter-Burundian dialogue resumes in Arusha, Tanzania at the initiative of the Tanzanian mediator, former President Benjamin Mkapa. The Burundian authorities demand that the opposition coalition CNARED should not be part of the dialogue. In June, the facilitator [Mkapa] travels to Brussels to meet members of the Opposition for the first time.

June 3: Eleven students from a high school in Muramvya, in central Burundi, were charged and jailed for insulting the head of state. Their crime: doodled pictures of President Nkurunziza. A week earlier, more than 300 college students from Ruziba, south of Bujumbura, were expelled from school for the same reason.

July 13, 2016. Hafsa Mossi, a former minister believed to be close to President Nkurunziza, is murdered near his home. A member of the ruling CNDD-FDD party, the former journalist was also the communications advisor for Nkurunziza. It is the first time a prominent political figure has been assassinated in Burundi.

The crisis in Burundi was on the agenda of the 27th AU Summit in Kigali in July, but it took place without a representative from Bujumbura. The Burundi delegation left the Rwandan capital without explanation just days before the start of the summit. No action was taken against the government of President Pierre Nkurunziza, who still refuses to negotiate with the opposition.
