North Koreans given prison sentences for spying in Ukraine...

Two North Koreans were reportedly arrested and sentenced to eight years in prison in Ukraine by intelligence authorities after they attempted to steal classified intelligence regarding missile technology. Ukrainian media report that Ryu Song-chul and Lee Tae-kil, both employees at a North Korean trade office in Belarus, traveled to Dnepropetrovsk in 2011 and were arrested after attempting to steal information from Yuzhnoye Design Bureau, which designs satellites and rockets. The North Koreans were said to be searching for intelligence regarding missile launch technology and increasing the range of its missiles with liquid fuel-fired engines. The North Koreans apparently received their sentence in late May on allegations of spying after Yuzhnoye employees informed authorities of their suspicious behavior.

Two South Koreans arrested for espionage for North...

South Korean police have arrested 2 men in connection with the recent jamming of global positioning systems that affected much of the country's air and maritime traffic. The 2 South Korean businessmen have been charged with violating the country's national security law. Police say North Korean spies met the two men in the Chinese city of Dandong last July and instructed them to collect intelligence information. They say the suspects had made contact with people in the South Korean military industry in the hope of collecting data on jamming devices and military technology. One of the suspects, in his 70s, was on parole after having been sentenced to life in prison 30 years ago in connection with another espionage case.
