Swastikas Daubed on Stockholm Mosque

Unknown perpetrators daubed black swastikas on the front door of a Stockholm mosque overnight, police said Thursday.

The incident happened amid growing concern about racism in Sweden, a country otherwise enjoying a reputation for tranquility and tolerance.

"When a staff member of the mosque turned up for work, he discovered that the entrance had been vandalized. Among other things, he found that several swastikas has been painted," police said in a statement.

Eight black swastikas could be seen on a photo posted on Twitter by the president of the Islamic Association in Stockholm, Omar Mustafa.

The mosque is located in a small street on the island of Soedermalm, near the center of Stockholm.

Last month, Neo-Nazis attacked a peaceful anti-racist protest in a Stockholm suburb, causing three people to be hospitalized.
