Reaction to the attempted bombing of a U. S. airliner on Christmas Day has been mixed among the six African nations with direct air links to the United States. Ghana has announced it will install full-body scanners at Accra’s international airport by next month. Nigeria has also announced it will install the scanners at Lagos international airport. They can detect non-metallic materials hidden on the human body. But some rights groups consider the scanners an invasion of privacy, because they show private physical characteristics in detail.

Egyptian archaeologists say they have discovered tombs of workers who helped build the country ’ s largest pyramid. As Keith Adams reports, the discovery sheds light on how they lived. The tombs made from bricks of dried mud date back 4, 500 years. According to Egypt’ s head of antiquities, Zahi Hawass, they revealed far from being slaves. Those who toiled on the Great Pyramid were free and enjoyed relatively good working conditions. He says their location, so close to the pyramid, which itself a tomb for their king, proves they weren’ t of the slave class.
