Unidentified gunmen shot and killed Burundi’s former army chief of staff yesterday in the second high-profile killing this month amid chaos linked to the disputed reelection of President Pierre Nkurunziza.

Col. Jean Bikomagu was shot dead outside his home in Bujumbura in the morning as he returned from church, said a witness who declined to give his name. His daughter, who was with him, was seriously wounded and rushed to hospital.

Gunmen killed a former Burundian security chief and close ally of Nkurunziza in early August. The next day, a prominent human rights activist who openly opposed Nkurunziza’s bid for a third term in office was shot and seriously wounded.

Another black weekend in Burundi

“Another black weekend in Burundi. Blackened by the assassination of a senior member of the Burundian army in retirement, Colonel Jean Bikomagu...Very sad, very shocking,” presidency spokesman Willy Nyamitwe said on Facebook.

Bikomagu was army chief during the civil war that started in 1993 when the Tutsi-dominated army was fighting then rebel leader, and now President, Nkurunziza’s CNDD-FDD Hutu rebels.

Nkurunziza was re-elected in July to a third term that opponents and Western powers said violated the Constitution and a peace deal that ended the civil war in 2005. The UN High Commissioner for Human Rights office in Geneva said at least 96 people had been killed since the start of election-related unrest in April.
