Japanese tournament under-mined

A golf tournament in Japan is hiring extra security because of threats that land mines have been buried around the course.

A mysterious caller reportedly warned that mines have been planted at the Kuroshio Country Club, site of the Casio World Open, which teed off earlier today (no explosions to report… yet).

Kochi Prefectural Police mobilised around 1,300 officers to secure the course ahead of the event, after an explosion there earlier this month, believed to have been caused by a hand grenade.
