A diplomat at the Japanese Embassy in Jordan repeatedly took home classified documents, potentially placing dignitaries at risk, a source said Thursday.
The 30-year-old second secretary at the embassy took home classified documents dozens of pages long on several occasions at least as far back as October 2012, the source said.
The papers contained details about overseas accommodations and meeting times for Prime Minister Shinzo Abe, senior officials' travel expenses and information about foreign leaders' plans to visits Japan.
The handling of classified information has been a major issue in Japan since the Abe administration late last year rushed through a law with harsher penalties for leaking secrets.
The Foreign Ministry said it is considering punishing the diplomat and will strive to prevent a repeat of the behavior.
