The country of Cuba is fuming after a rumor that Fidel Castro was dead spread across Twitter.

Cuba quickly refuted the trending story, with Martin Castro, Fidel's half-brother, telling The Huffington Post It's a lie, a big lie! He's resting now. But he's more or less fine.

Castro, no stranger to rumors, apparently laughed off the news of his death.

Fidel Castro studied, analyzed and is laughing at the rumors on Twitter, wrote official blogger Yohandry Bloquera. The CIA tried to kill him more than 700 times and Twitter is going down that road.

But the Cuban government did not take the rumor as lightly. The country's state media condemned the social media network for allowing the disinformation to trend and claimed that Twitter was supporting necrophiliac counter-revolutionaries.

As you know we don't mediate content, Twitter spokesperson, Jodi Olson, told the Associated Press.

Cuba believes that it has tracked down the originator of the death rumor, tracing it to @naroh, a Spanish user named named David Fernandez.

However, Fernandez denied that he was the first to post about Castro, claiming that he only retweeted posts and made a few jokes, which is evident from his account activity.

Cuba has blamed me for killing Fidel Castro on Twitter. Can I consider myself a twitstar? Fernandez commented.

They should double-check their 'information' before blaming someone for no reason, Fernandez told CNN on Wednesday night . I wrote about that when the topic was already trending and my tweets were mostly jokes. I didn't start anything.

The hashtag #fidelcastro started trending some time on Jan. 2 and in the following days became the fourth most popular subject on Twitter in the world.

Celebrity death rumors have become a trend unto itself. Most recently, there was a rumor that 1980s rock star Jon Bon Jovi had died. Other celebrities who have died in recently include Denzel Washington, Ruby Dee, Bill Cosby, Nelson Mandela, Aretha Franklin and Morgan Freeman.
