Declassified spy images of Iraq have helped archaeologists find a historic Islamic battlefield.
Upon analyzing the images, which were taken in 1973 by a U.S. satellite system named KH-9 (Hexagon), the team found remnants of a 1,400-year-old settlement. This helped them match the site to the lost location of the Battle of al-Qadisiyyah, the researchers reported in a study published Nov. 12 in the journal Antiquity.
