Vandals have broken into a Stockholm mosque and spray-painted Nazi swastikas and messages of hate on its walls.

Only one worshiper was present in the mosque in Bredäng, a southern area of the Swedish capital, when the unidentified attackers entered.

A spokesperson for the mosque told the TT news agency, the man was left shaken but unharmed after the incident.

Stockholm police have said officers are investigating the incident as a case of vandalism and hate crime. No arrests have yet been made, The Local reports.

Mustafa Turnturk, who was one of the mosque's founders in 1985 and a representative of the Stockholm Muslim community, said he could no longer recognise his country.

Mr Turnturk said: "This is not something one would expect...It's hard to understand what is going on in society, both internationally and in our own country. I don't recognise Sweden anymore."

As Sweden has received record numbers of refugees - 245,000 in 2014 and 2015 - the number of attacks on mosques and refugee centres have increased.
