Projectiles from renewed fighting in Ethiopia struck refugee camps in eastern Sudan, shattering a fragile safe haven for thousands of displaced people.
Sudan confirmed multiple casualties among camp residents, but said the exact death toll has not yet been verified.
The shells hit the camps as Ethiopian government forces clashed with fighters from the Tigray region, undermining a fragile peace that had held for nearly two years.
Families who fled conflict in Ethiopia now face renewed violence after the fighting spilled across the border into Sudan.
Officials warn the latest escalation could trigger another wave of displacement along the already unstable Sudan-Ethiopia border.
Sudan hosts about 63,000 Ethiopian refugees, most of them living in the eastern border states of Gedaref and Kassala.
More than 34,000 refugees live in the Al-Tunaydaba and Um Rakuba camps, which were directly affected by the cross-border shelling.
Sudanese authorities have called for urgent international support to protect the camps and provide emergency humanitarian assistance.
