Tokyo has ordered all diplomatic offices abroad to beef up security after the Islamic State militant group called on its supporters to attack Japanese missions in Indonesia, Malaysia and Bosnia-Herzegovina, Chief Cabinet Secretary Yoshihide Suga said Friday.

The militant group issued the message in the latest edition of Dabiq, its English-language magazine whose copies are circulated over the Internet.

Japanese expats in the three countries are also urged to be conscious about their safety, Suga added.

¡°We are aware that such an article has been carried (in the magazine). We are cooperating with host countries to guard the overseas government offices,¡± Suga said.

After the militant group killed two Japanese hostages earlier this year, the magazine published photos of the victims, 42-year-old Haruna Yukawa and 47-year-old Kenji Goto.

The magazine said the group executed the two to ¡°humiliate the arrogance of this Japanese government,¡± and accused Japan of having been a player in the wars in Iraq and Afghanistan.
