Somali pirates have released a Greek chemical tanker seized in October but three crewmembers are feared dead, a Kenyan maritime official said Saturday. "The MT Action was released by pirates," Andrew Mwangura, who heads the Kenyan chapter of the East African Seafarers Assistance Programme, said in a statement. "She is currently limping to safe waters. It is feared that three crew members lost their lives under questionable circumstances," he added.
