In March 2018, UN Secretary-General António Guterres reappointed Mohamed Chande Othman, Tanzania’s former chief justice, to continue his investigation into the circumstances of the crash.
The Secretary-General also urged Member States to actively assist the Eminent Person in the performance of his mandate, and called on Member States “that may hold information relevant to the Dag Hammarskjöld investigation to appoint an independent and high-ranking official to conduct a dedicated internal review of their intelligence, security and defence archives to determine whether relevant information exists”.
