The Red Cross began the hotline at the behest of Mona Sahlin, national coordinator against violent extremism.
"As national coordinator, I found out early that there is a great need of support for those who are near to the people involved in violent extremism. It could be the mother, the brother, soccer coach, teacher or social worker," said Sahlin in a press statement.
Radio Sweden spoke with Anna Carlstedt, the president of the Swedish Red Cross. Carlstedt said that this sort of hotline has been successful in other countries. Callers can be connected with support groups or can simply hear that they are not alone.
"People calling think they're totally alone in this situation," she said.
The telephone line will open November 16 and will be available on weekdays from 9 a.m. to 3 p.m. In June organizers will decide whether to make the hotline permanent.
