Ethiopia declared a six-month nationwide state of emergency early October following the unrest occurred in some areas.
The state of emergency was declared following a thorough discussion by the Council of Ministers on the loss of lives and property damages occurring in the country.
This week, the country lifted the directive which restricts diplomats from travelling beyond a-40 kilometers radius out of Addis Ababa without the permission of the command post.
