A Swedish artist has been sentenced to six months in prison for works a court said depicted Roma and black people in a racist way.

Dan Park was convicted on Thursday of defamation and inciting hatred against an ethnic group.

The case focused on nine framed posters by Park that were seized from an art gallery in the city of Malmo in July.

One depicted three black men with nooses around their necks. Another showed Roma community leaders with text suggesting they condoned crime.

It is unusual for Swedish courts to hand out prison terms for art works. Park, who has several similar convictions, said his works were satirical and claimed the right to freedom of speech.

The gallery's owner received a conditional sentence and fines of 7,500 krona (£656).
