A forgotten city thought to date back as far as the 10th century AD has been uncovered by a team of archaeologists in eastern Ethiopia.
Artefacts from Egypt, India and China have been found in the city in the Harlaa region.
The archaeologists also uncovered a 12th Century mosque which is similar to those found in Tanzania and Somaliland. ... The team also found jewellery and other artefacts from Madagascar, the Maldives, Yemen and China.
Harlaa was a "rich, cosmopolitan" centre for jewellery making, Prof Insoll said.
"Residents of Harlaa were a mixed community of foreigners and local people who traded with others in the Red Sea, Indian Ocean and possibly as far away as the Arabian Gulf," he said.
