A team of American and Bosnian archaeologists claim to have found two new pyramids buried under hills in Central Europe.
The scientists say they found ancient labyrinths and other sand
stone buildings under two unusually shaped hills in central
They believe the ruins indicate the hills were once human settlements, probably built by a stone age "super" civilisation tens of thousands of years ago.
They are now trying to locate ancient stairs that would lead them to the entry of the pyramids.
