Crowds converged on the area on 6 April and five days later, long-time leader Omar al-Bashir was ousted and arrested by the military after nearly 30 years in power.

The hashtag #Sudaxit has been popular with the protesters and harks back to Sudan’s African, rather than Arab, identity. This graffiti says: “We demand that Sudan leaves the Arab League. We are black people, the sons of Kushites” – a reference to the ancient Kush kingdom.

It goes on to demand the return of the the Hala’ib Triangle, disputed land between Sudan and Egypt.
