South Korean prosecutors indicted a social media and free speech activist on Tuesday for reposting tweets from a North Korean government website. Photographer Park Jung-geun was detained last month on charges of violating South Korea’s National Security Law, which broadly bans “acts that benefit the enemy”. Park was interrogated by detectives following a police raid on his photo studio last autumn. Park has said the tweets — which included reposting North Korean propaganda messages such as “long live Kim Jong-il!” and links to North Korean propaganda songs — were intended to mock the North Korean regime.
