Somaliland: The brightly coloured and beautifully preserved rock paintings, depicting domesticated animals, could be up to 5,000 years old. Men are depicted riding on the back of some of the animals, or with raised arms, as if worshipping the cattle. Wild animals such as giraffes - which no longer exist in this rocky, arid climate - also appear, suggesting a shift in weather patterns since the paintings were made. "We all agree that this is an important discovery," says Lazare Eloundou Assomo, chief of Africa at the Unesco World Heritage Centre. But as Somaliland is not recognised by the UN, and Somalia has not ratified the 1972 World Heritage Convention,there is no question of the site getting world heritage status in the near future.
