Eritrea-Ethiopia Fighting Puts Red Sea Corridor at Risk

Ethiopia and Eritrea have both closed their embassies and are exchanging allegations of military aggression, with Eritrean forces reported up to 60 kilometres inside Ethiopian territory and Ethiopian drones striking Eritrean troops near the border town of Adigrat.

Eritrea's Information Minister Yemane Gebre Meskel said on October 7 that Ethiopia's ruling party is pursuing a military plan to establish a presence along Eritrea's southern coast, with the port of Assab as the ultimate objective. A senior Ethiopian general reportedly stated that Ethiopia intends to plant its flag on the Red Sea. Eritrea, which has controlled a long stretch of the western Red Sea coast since independence in 1993, rejects the framing. Ethiopia's foreign minister wrote to the UN Security Council on October 8 accusing Eritrea of sending forces 60 km into Ethiopian territory. The Armed Conflict Location and Event Data Project recorded Ethiopian drone strikes on Eritrean forces and vehicles near Adigrat on the nights of October 8 and 9.

The standoff is drawing in neighbours. Egypt, Sudan, Eritrea, and Somalia met at El Alamein on Sunday and agreed to coordinate military and intelligence activities if the conflict expands. They also rejected any recognition of Somaliland, a position that cuts against Ethiopia's recent diplomatic moves. On the other side, Ethiopia has received drone systems and weapons from the UAE and Israel. The US Embassy in Addis Ababa has warned of possible long-range strikes on military infrastructure in the capital, and the US State Department has urged both countries to exercise restraint.

The maritime stakes are rising. Eritrea's coastline runs about 1,000 kilometres along the western edge of the southern Red Sea, directly above the Bab el-Mandeb chokepoint where the Red Sea meets the Gulf of Aden. With the Strait of Hormuz under a US-Iranian blockade since February, oil and container traffic have shifted more heavily into the Red Sea, making the corridor more exposed. MarineRadar is tracking 87 unique-device sessions per 48 hours in the Southern Red Sea Eritrea region, with vessels moving through a zone now bordered by active Houthi operations to the north and a potential new armed front along the Eritrean coast. The same waters have already seen an armed attack on CUL Klang in the Southern Red Sea and the 35-day pirate hijacking of the Eritrea-flagged Sibu 1 in the Gulf of Aden, both events that show how quickly maritime incidents multiply when state authority frays along the coast.

No commercial vessel has been struck in connection with the Ethiopia-Eritrea conflict as of October 10. How far the fighting spreads, and whether either side moves against the other's coastline, will determine whether the Red Sea corridor faces a new armed front on top of the Houthi and Hormuz pressures it already carries.
