Dan Eliasson

The Swedish government has begun sending all 4.8m of the country's households a public information leaflet telling the population, for the first time in more than half a century, what to do in the event of a war.

Swedish National Police Commissioner Dan Eliasson has begged the government for help as the number of no-go zones has risen from 55 to 61 in only one year.

A 39-year-old Uzbek man being held in custody is the suspected driver of a hijacked beer delivery truck that ploughed into crowds in central Stockholm, killing four people and wounding 15 in an apparent terror attack, police have said.
