Somali pirates release four S Koreans after 582 days in captivity

Somali pirates have released four South Korean sailors after holding them captive for nearly 19 months.

Their tanker - the MT Gemini - was hijacked in April 2011 on its way from Kenya to Malaysia, but they were not among the 21 non-Korean sailors released seven months later.
