A picture taken on January 23, 2015 shows the burial mask of Egyptian Pharaoh Tutankhamun, who ruled Egypt from 1334 to 1325 BC, at the Cairo museum in the Egyptian capital. An Egyptian conservation group said it would sue the antiquities minister over a 'botched' repair of the mask of Tutankhamun that left a crust of dried glue on the priceless relic.
