K-pop star Jin of BTS starts his military service in South Korea

The 30-year-old begins five weeks of training amid questions over future of the global phenomenon band

Jin, the oldest member of the K-pop phenomenon BTS, was due to begin his mandatory military service on Tuesday at a base close to the border with North Korea, amid growing speculation about the band's future.

The 30-year-old, now sporting a buzzcut, will be followed into the military by younger members of the band in the coming years, after their impending enlistment sparked a debate among South Koreans over whether the band, and other successful entertainers, should be granted exemptions.
