In monthly meetings on human rights organized by OHCHR, members of the diplomatic community in Bujumbura have long expressed concern about the problem of impunity for past crimes, but have failed to take concerted action. In February 2008, responding to the surge of killings in Bujumbura, several members of the diplomatic community present at one such meeting proposed a joint letter from BINUB, the African Union, and the European Union to President Nkurunziza expressing concern that impunity for past crimes was contributing to current violence. Though others present at the meeting expressed support, they proceeded to back out one by one. Over a year later, no such letter had been delivered, though impunity remained a problem.[269]
