South Korean held in Russia for spying did humanitarian work, aid group says

A South Korean missionary, Baek Kwang-soon, was arrested in Russia on espionage charges, causing strain in Russia-South Korea ties. Baek's aid group denies the charges and states he was doing humanitarian work. South Korea is communicating with Russia for Baek's release. Ties between Russia and South Korea have been increasingly strained by Moscow's growing relations with North Korea.
