Ethiopians and Eritreans have been celebrating the reopening of two key crossing points more than 20 years after a border war shut them.
Hundreds of people from the two countries hugged each other and some wept as their leaders led celebrations to mark the reopening.
Ethiopia also announced that its troops would start withdrawing from the border area.
These are the latest moves in the rapprochement between the ex-enemies.
Ethiopian Prime Minister Abiy Ahmed and Eritrean President Isaias Afwerki signed a peace deal in July, restoring diplomatic and trade relations between the nations.
The reopening at Burre gives landlocked Ethiopia access to the sea. Another border post, near the Ethiopian town of Zalambessa, also reopened.
