Lieutenant General Abdul Rahim Dagalo, the deputy commander of Sudan’s Rapid Support Forces (RSF), has travelled urgently to Chad as tensions escalate along the border.
The visit follows reports after Chad’s government said the incursion killed seven Chadian soldiers and wounded others.
Sources said Dagalo sought to contain the crisis and reassure Chadian leaders amid growing military activity.
He reportedly told officials he had information suggesting Chadian soldiers had taken part in fighting against RSF forces in the Djurdjura area.
Fighting near Djurdjura and Konwe has heightened anxiety, with rival forces gathering on both sides of the border.
Chadian authorities said that any such presence was the result of tribal mobilisation in the east, not official military involvement.
However, images circulating online showed destroyed vehicles with Chadian licence plates, supporting allegations of direct Chadian military involvement.
Tensions reportedly surged after RSF took control of Abu Qumra and Jarjira in northwest North Darfur.
Other sources reported heightened alert in Sudanese refugee camps in eastern Chad, where some fighters were allegedly being mobilised.
Chad has replaced several senior security officials in the east to tighten control and curb armed movements.
Meanwhile, RSF reinforcements have been deployed around Al-Tina, as preparations continue for a possible assault on the border town.
Sources said RSF leader Mohamed Hamdan Dagalo, known as Hemedti, ordered his forces to avoid harming civilians.
Analysts warn the crisis risks igniting a wider cross-border tribal conflict along an increasingly volatile frontier.
