Ukraine president gives Crimea leaders three hours to release navy chief

Ukraine's acting president on Wednesday said Crimea's separatist leaders had three hours to release the detained head of the ex-Soviet state's navy or face "an adequate response".

Acting president Oleksandr Turchynov said in a statement that "unless Admiral (Sergiy) Gayduk and all the other hostages -- both military and civilian ones -- are released, the authorities will carry out an adequate response... of a technical and technological nature."
