On Saturday, several of Swedish Radio's twitter accounts were hacked and a number of strange and obscene posts were posted in the names of the accounts.

Although it was clear that the message was not from Swedish Radio, the incident is serious, says Gazmend Huskaj at the Swedish National Defense College:

- If you lose confidence in a trusted channel that reaches out with news and information, it will be difficult to get information that is correct in a crisis or equivalent. 

Gazmend Huskaj makes a comparison with an incident in 2013 when someone infringed and took over the news agency Associated press twitter account.

The account then tweeted that the then US President Barack Obama was injured in two explosions.

- After that, Wall street leaf box fell until the news came that he was unharmed, says Gazmend Huskaj.
