Warning: Story contains major spoilers

The next episode of “Game of Thrones” has been accidentally broadcast by HBO Spain, four days before it was due to air.

And stills from the episode reveal the Night King acquiring a new weapon that should strike fear into the whole of Westeros.

The snaps appear to feature the ice zombie having gotten his own dragon — with the beast boasting icy blue eyes much like the rest of the army of the dead.

It’s not yet clear if the Night King turned one of Daenerys’ beloved dragons into one of his dead army.

Spanish subscribers were able to access the episode on demand for one hour before it was removed, according to reports.

But it was available long enough for the episode to be shared online on a slew of streaming services.

The news comes as a blow to HBO, which has struggled with spoiler episodes hitting the web.

Scripts have also been released after a hacker breached HBO’s computer network, and on Tuesday, Indian police arrested four people over a leak of Episode 4 of the current season.

The leaks have included scripts, internal documents and emails from an executive so far and it is feared more will follow.

Unreleased episodes of “Curb Your Enthusiasm,” which makes its much-anticipated return in October, and other shows have been dumped online, according to reports.

HBO said it is not in contact with the group and conceded further “bits and pieces” of stolen information may follow to generate “media attention.”

“That’s a game we’re not going to participate in,” the channel’s statement added.

“Obviously, no company wants their proprietary information stolen and released on the internet.”

“Game Of Thrones” star Nikolaj Coster-Waldau has said ratings will not be damaged by leaked episodes as well as spoilers released after the HBO hack.

The actor — who plays Jaime Lannister on the show — said he believes most true fans will stay away from compromised information.

He said: “There were always going to be people who want to find out more but I think it’s just a tiny, tiny fraction of the people who love the show.”

“Why would you want to spoil it for yourself?

“We saw it last week, there was an episode leaked, Episode 4 was leaked, that didn’t hurt the ratings at all.”

An official trailer for next week’s episode was released yesterday showing Jon Snow, who is played by Kit Harington, and his band of brave men venturing north of The Wall to capture a White Walker and battle the Night King and his army of the dead.

But their task is made all the more daunting as the terrifying icy zombies launch their attack.
