A Sudanese security source in the border town of Hamdayet said arrivals from Tigray included wounded fighters. ExplosionsResidents on the Sudanese side of the border reported hearing explosions and sustained gunfire throughout the fighting. Fighting has been taking place in the contested area of western Tigray, which is controlled by nationalists from the neighbouring Amhara region. In May, Ethiopia accused the Sudanese army of backing TPLF-linked “mercenaries”, while Sudan accused Ethiopia of allowing drone attacks to be launched from its territory in coordination with the United Arab Emirates.
