Armed robbers have stolen dozens of artefacts from a museum in Ancient Olympia - the birthplace of the Olympics, Greek officials say. They say two masked men smashed glass displays after overpowering a guard. Local mayor Thymios Kotzias said items of “incalculable” value had been stolen, but gave no details. Culture Minister Pavlos Geroulanos has tendered his resignation, but it has so far not been accepted. He is on his way to the site in western Greece. The armed thieves are reported to have entered the museum at 07:30 on Friday (05:30 GMT) and demanded that a female employee hand over various objects. When the employee refused she was tied up and gagged. The two men then smashed cabinets, stealing more than about 60 items, mostly bronze and clay statuettes, officials say.                          –BBC
