U.N. Secretary-General Kofi Annan has called on the U.N. Security Council to ensure Eritrea lifts restrictions on U.N. peacekeepers.

In a letter to the Security Council Tuesday, Mr. Annan described the situation on the Eritrea-Ethiopia border as "alarming." He said it requires the full attention of the international community.
