On May 13, 2015, a coup d'état was attempted, led by Major General Godefroid Niyombare, while President Nkurunziza was in Tanzania attending an emergency conference about the situation in the country. By the next day the coup collapsed and government forces reasserted control. At least 240 people were killed over the next few months, and on December 11, 87 people were killed in attacks on state targets. Violence continued through 2017.
