Sweden said it will issue another update of a Cold War-era civil emergency advice booklet later this month, with the new version “adapted to better reflect today’s security policy reality” such as what to do in case of nuclear attacks.

The booklet, “If Crisis or War Comes,” includes lessons learned from Russia’s invasion of Ukraine, officials said Tuesday.

“It is no secret that the security situation has deteriorated since the previous brochure was issued in 2018,” Swedish Civil Defense Minister Carl-Oskar Bohlin told a press conference.

He said that the military threat against Sweden has increased and an armed attack cannot be excluded. “The threat picture is more complex than earlier and includes cyberattacks, influence attacks and risk of sabotage,” Bohlin said.
