Sweden's dilemma over immigration controls

Sweden, which has received more than 100,000 asylum seekers this year, has announced it had decided to impose temporary border controls.

The migration authorities say they are overstretched, and that relative to population size, Sweden has already taken far more migrants than any other EU country.

In recent weeks there have been several attacks on residential centres for asylum seekers, and far-right groups are claiming increasing support.
