The New York premiere of The Interview, a comedy about the assassination of North Korea's president, has been cancelled amid threats from hackers, the BBC reports.
Hackers targeting Sony Pictures had threatened to attack US cinemas showing the studio's film, the BBC reported.
Calling themselves Guardians of Peace, the hackers mentioned the 9/11 attacks in a recent warning, claiming “the world will be full of fear”.
“Remember the 11th of September 2001. We recommend you to keep yourself distant from the places at that time,” the hacker group wrote in a message this week.
“If your house is nearby, you'd better leave,” they add. “Whatever comes in the coming days is called by the greed of Sony Pictures Entertainment.”
The Department of Homeland Security said there was “no credible intelligence to indicate an active plot” against cinemas, but noted it was still analysing messages from the group.
