The majority of the stranded students are females who have yet to be documented by Nigerian authorities, and they are reportedly in danger.
Aliyu Abdulkadir, the president of SOSAN, expressed concern that the students were left without food, water, and money, while gun battles had already reached the university environs.
Even the much-touted 5,000 students who have been transported to Egypt were yet to leave Egyptian border, with some dropped in the bush by their bus drivers due to non-payment.
The Nigerian Ambassador to Sudan, Safiu Olaniyan, has given assurances that embassy officials are working to ensure their evacuation, but the embassy is not in charge of hiring buses to convey evacuees out of Sudan.
He pleaded with those aggrieved to rethink any alleged plan to attack embassy officials.
Efforts are still being made to convince the Egyptian authorities to allow Nigerians fleeing Sudan to pass through their country, from where they would be flown back home.
