The United States says it will send a team of diplomats to the Horn of Africa region to try to resolve the border dispute between Eritrea and Ethiopia.

The U.S. ambassador to the United Nations, John Bolton, says the delegation will focus on "how to begin implementation of the border demarcation process."

He said the delegation will be led by U.S. Assistant Secretary of State for African affairs Jendayi Frazer.

Mr. Bolton spoke to reporters after the U.N. Security Council discussed Eritrea and Ethiopia in a closed-door meeting Monday.

Eritrea says the U.N. has done too little to make Ethiopia accept a borderline drawn by an independent panel.

U.N. officials have said the situation on the two countries' border remains "tense and potentially volatile." Eritrea and Ethiopia fought a border war between 1998 and 2000 that killed 70,000 people.
