SEOUL, South Korea (AP) South Korean prosecutors indicted a left-wing lawmaker Thursday on charges that he was plotting a pro-North Korea rebellion to overthrow the government, saying his plan posed a "grave" national security threat.
Lee Seok-ki, from the small United Progressive Party, was arrested by South Korea's spy agency earlier this month for allegedly discussing launching strikes on national infrastructure with his colleagues in May in the event of a war with North Korea. The National Intelligence Service later handed him over to prosecutors.
Lee has flatly denied the allegation, saying the spy service fabricated the charges to divert criticism that its agents allegedly posted online messages supporting the conservative ruling party candidate and now-President Park Geun-hye and smearing her main liberal rival ahead of December's presidential election.
The case triggered a massive political and media firestorm in South Korea, with critics raising questions over whether there is any substantial evidence to back up Lee's alleged rebellion plot and noting past military-backed authoritarian governments often used rebellion charges to suppress political rivals.
North Korea angrily reacted to the scandal, calling it a "witch hunt" targeting those espousing greater reconciliation on the Korean Peninsula. North Korea last week cited the rebellion plot as an example of South Korea's confrontational postures that forced it to cancel this week's planned reunions of families separated by the 1950-53 Korean War.
