A joint A US and Egyptian archaeological team say they have found the largest funerary complex yet dating from the earliest era of ancient Egypt, more than 5,000 years ago in the Kom al-Ahmar region, around 600 km (370 miles) south of the capital, Cairo. Inside the tombs, the archaeologists found a cow’s head carved from flint and the remains of seven people. They believe four of them were buried alive as human sacrifices. The complex is thought to belong to a ruler of the ancient city of Hierakonpolis in around 3600 BC, when it was the largest urban centre on the Nile river.
