Edward Snowden may have been captured or killed.
A coded tweet by former CIA agent Edward Snowden has sparked conspiracy theories that the whistleblower may have been captured or killed
The 33-year-old fled to Russia from the US after leaking top secret documents.
On Wednesday he took to Twitter and posted a series of messages which some took to indicate he may have been about to reveal another batch of classified information.
His first tweet said: ” “Did you work with me? Have we talked since 2013? Please recontact me securely. It’s time.”
On Friday he followed up with another post, which contained 64 seemingly random characters .
Both of the messages have since been deleted.
Various theories have started to surface about what the posts could mean.
