[...] Ahmed Bashir, from Khartoum, who has been in Wadi Halfa since late April, says that in his third week, he was disheartened to hear that volunteers tasked with helping people process their visas were accepting bribes to fast-track the process. Payments amounted to roughly $1,000 on the black market, he claims. The Al Salam school in Wadi Halfa has become a de facto shelter for dozens of those fleeing the violence, and to the safety of the unknown.
