The African Union urged Djibouti and Eritrea to remain calm and exercise restraint on Saturday after Djibouti accused its neighbor of occupying disputed territory along their border following the withdrawal of Qatari peacekeepers.
On Friday, Djibouti’s Foreign Minister Mahamoud Ali Youssouf said Eritrean troops had seized Dumeira Mountain and Dumeira Island, areas the neighbors contest, and his country’s military was on alert.
Authorities in the Eritrean capital Asmara were not available for comment.
Qatari peacekeepers were previously deployed along the frontier. Doha announced on June 14 that it had pulled its contingent out, days after the East African countries sided with Saudi Arabia and its allies in their standoff with Qatar.
In a statement, the African Union Commission’s Chairperson Moussa Faki Mahamat appealed for calm.
“The AU Commission, in close consultations with the authorities in Djibouti and Eritrea, is in the process of deploying a fact-finding mission to the Djibouti-Eritrea border,” he said.
Clashes broke out between the Horn of Africa countries in June 2008 after Djibouti accused Asmara of moving troops across the border, raising fears the spat could engulf the region.
The dispute triggered several days of fighting in which a dozen Djiboutian troops died and dozens were wounded. Eritrea had initially denied making any incursions, accusing Djibouti of launching unprovoked attacks.
At the time, the U.N. Security Council requested both sides withdraw, before the neighbors accepted a Qatari request to mediate and deploy peacekeepers.
Qatar has not given reasons for its withdrawal, but it comes amid a diplomatic crisis with some of its Arab neighbors. They cut ties a week ago, accusing Qatar of backing Islamist militants and Iran – claims Doha strongly denies.
