North Korea calls for joint inquiry over Sony Pictures film
Sony Pictures Entertainment has said it still wants to release its film The Interview, a satire featuring an assassination plot against North Korean leader Kim Jong-un, and it is considering alternative platforms.
The remarks come after President Obama said the film company made a mistake by cancelling the movie's release.
The president also said that the United States would respond to the cyber-attack on Sony Pictures.
