The top United Nations official in Libya Tarek Mitri, head of the United Nations Support Mission in Libya (UNSMIL), briefed the UN Security Council on January 29th regarding the situation in that beleaguered country. He provided a mixed report. He saw some reason for optimism with regard to institutional reforms and improvements in security, but said that Libyan authorities would still need to make tough decisions on such key issues as constitution-making, transitional justice and security sector reform.
