US, African Union warn of regional spillover after Sudanese strikes in Chad

August 27 2026 (KHARTOUM) – The United States and the African Union have warned against the regional expansion of Sudan’s war following reports of air strikes conducted by the Sudanese military inside neighbouring Chad.

U.S. Senior Advisor for Africa Massad Boulos condemned the strikes in Chadian territory on Wednesday, saying there is no justification for expanding the violence beyond Sudan’s borders.

Boulos called for an immediate humanitarian truce and urged the United Nations Security Council to urgently update its sanctions regime and arms embargo to halt external military and financial backing for the warring parties.

African Union Commission Chairperson Mahmoud Ali Youssouf also voiced deep concern over the reported Aug. 20 strikes in Chad’s Ennedi-Est region, calling on all sides to respect national sovereignty and the inviolability of borders.

Youssouf urged maximum restraint and called for stronger regional cooperation to secure shared frontiers and prevent cross-border escalation.

The statements follow accusations by Chad’s military on Saturday that Sudanese aircraft and drones struck a convoy of vehicles more than 100 km (60 miles) inside Chadian territory.

Chad subsequently placed its armed forces on high alert, warning that it reserved the right to defend its territorial integrity.

Sudan’s army has previously accused Chad of allowing the United Arab Emirates to funnel weapons and supplies through Chadian airports to the paramilitary Rapid Support Forces (RSF). Both Chad and the UAE have denied the allegations.

Sudanese authorities and the military did not immediately comment on the U.S. and AU statements.
