Daily SumUp

Scientists who revealed an underground 'hidden city' in Egypt have announced the discovery of a second city they say 'proves' the existence of a massive subterranean complex linking the Giza pyramids 2,000 feet beneath the surface.

The newly-discovered shafts and chambers could rewrite history if confirmed to be true.  

The team of Italian researchers first claimed to have uncovered vast underground structures below the Khafre pyramid in March, igniting fierce backlash from mainstream archaeologists who called the findings 'false' and lacking scientific basis.
