Thieves stole four diamonds worth several million dollars from a trader's stand at the world's biggest watch and jewellery fair in Basel on Wednesday, prosecutors said. "Three men engaged the staff in a sales talk while one or two others opened the showcase," said Markus Melzl, spokesman for the Basel prosecutor's office. "These were real pros who had done some research ahead."
