Rubio Warns Ethiopia–Eritrea Border Fighting Could Widen Into War

US Secretary of State Marco Rubio has warned that the confrontation along the Ethiopia–Eritrea border risks becoming a wider war, saying troops are now surging on both sides of the frontier. His comments came as Washington simultaneously relaxes its sanctions posture toward Eritrea and maintains targeted visa restrictions on officials linked to the Tigray People's Liberation Front (TPLF).

Key facts

• Rubio said armed groups he described as separatists attacked inside Ethiopia and that Ethiopia responded, with forces building up on both sides of the border.
• He warned the situation could become "a broader conflict" and pull in other countries.
• In a call with Prime Minister Abiy Ahmed days earlier, Rubio called for de-escalation and dialogue under the 2018 Ethiopia–Eritrea peace framework.
• The United States imposed targeted visa restrictions on TPLF officials in June 2026.
• Washington lifted restrictions on defence exports to Ethiopia in February and ended the sanctions regime under Executive Order 14046 in September.

What did the US say about the border fighting?

Rubio described the reported attacks inside Ethiopia as terrorist attacks while urging Addis Ababa to respond wisely and measuredly. In his earlier telephone call with Prime Minister Abiy Ahmed, he called for de-escalation by all sides, dialogue under the 2018 Ethiopia–Eritrea peace framework, respect for sovereignty and territorial integrity, and an end to cross-border incursions.

The remarks came against a backdrop of escalating confrontation between the federal government and the TPLF, alongside rising tensions between Ethiopia and Eritrea. Reports cited in the same context describe Eritrean forces advancing tens of kilometres into Ethiopian territory.

What travel and visa measures are in place?

In June 2026 the State Department announced targeted visa restrictions on individuals it accused of undermining efforts to resolve the crisis in Tigray, singling out TPLF officials. In September, US Ambassador Ervin Massinga said the TPLF leadership had made the "poor decision to launch a large-scale offensive" after the seizure of the airports in Mekelle, Axum and Shire, and warned that the United States could impose further sanctions.

At the same time, Washington has been easing measures elsewhere: restrictions on defence exports to Ethiopia were lifted in February, and the sanctions regime established under Executive Order 14046 was terminated in September, removing designated individuals and entities from the US sanctions list.

What is happening with Eritrea?

The United States has indicated it is gradually reopening diplomatic channels with Eritrea, including through sanctions relief and renewed contact, so it can speak to both sides. Washington's interest is linked to the strategic importance of the Bab el-Mandeb strait and the vulnerability of Red Sea shipping.

What this means for travellers

The risk of a wider confrontation involving Ethiopia and Eritrea, with forces reported on both sides of the border and airports in Tigray having changed hands, is a factor for anyone planning travel to the region. Red Sea shipping has also been identified as potentially affected. Travellers should check current entry rules and any visa restrictions that apply to their nationality before booking.

No new dates or measures have been announced. Washington's approach will depend, on the assessment set out in the analysis, on whether renewed engagement with Asmara produces concrete changes on the ground.
