On a continent that has long attracted western expeditions, a wave of young people are now exploring sites

A late morning in Khartoum. Inside a low, dusty building in the centre of the Sudanese capital, there are crates of artefacts, a 7ft replica of a 2,000-year-old stone statue of a Nubian god, and students rushing through the corridors. Outside is noisy traffic, blinding sunlight and both branches of the Nile.

Heading down one staircase are Sabrine Jamal, Nadia Musa, Athar Bela and Sabrine al-Sadiq, all studying archaeology at Khartoum University. Not one of them is older than 24 and they see themselves as pioneers, breaking new ground on a continent that has long attracted western expeditions, specialists and adventurers but whose own archaeologists have received less attention overseas.
