As if Greece didn't have enough problems: A pair of armed robbers have stolen dozens of artifacts from a museum located at the birthplace of the Olympic Games, the BBC reports. The stolen items, mostly bronze and clay statuettes, were of "incalculable" value, officials say. Police say the robbers smashed glass display cases with hammers after immobilizing a female guard. Greece's culture minister submitted his resignation after the robbery. (More museum theft stories.)
