Richard Oehme told Radio Sweden that coordination was needed with companies like Facebook and Snapchat now young people no longer get their news from radio and TV.
"Very young people get everything from social media...and you have to be able to reach them when something bad happens because the media is really important to get out to the public during a crisis," Oehme said. "I think we need to form a new alliance with the big social media vendors."
The Swedish Civil Contingencies Agency released a report on Monday, titled "Threats, Risks and Vulnerabillities in the Media Industry".
The report warned that digital media had increased the risk of false information and propaganda spreading, that viral news could trigger societal unrest, that media companies could be hacked, and that the fragmentation of the media could make it more difficult for the government to communicate with the public in a crisis.
Oehme told Radio Sweden that some social media companies were already developing services that could be used in a crisis, but that not all were cooperating with government.
