Eritrean President Isaias Afewerki is criticizing the U.N. Security Council for failing to force Ethiopia to accept an international ruling on a new post-war border.
In a letter to the council, the Eritrean president said members have lost credibility and moral authority due to its unwillingness to enforce the rule of law and respect for territorial integrity of a U.N. member state.
President Afewerki was referring to Ethiopia's refusal to implement an independent border ruling that awarded the hotly contested town of Badme to Eritrea.
The United Nations has criticized Eritrea for banning helicopter flights by U.N. peacekeepers last month, saying the ban has severely hampered its ability to carry out its mission.
The ban raised concerns Eritrea might be concealing troop movements in preparation for resuming fighting with Ethiopia.
The two Horn of Africa nations fought a two-year border war, which claimed some 70,000 lives.
