An ancient Spanish town that voted to change its name because it was deemed anti-Semitic has come under attack from extremist groups who have daubed the town's signposts and buildings with offensive right-wing symbols and messages protesting the change.

Castrillo Mota de Judios ("Jews' Hill Camp") town mayor Lorenzo Rodriguez Perez said Thursday that after the latest weekend attack the town had decided to file a complaint with police.

The village of some 50 inhabitants voted in 2014 to change its name from Castrillo Matajudios ("Camp Kill Jews") to its current form. Rodriguez said that since then there have been six vandalism incidents as well as protests whenever Jewish or Israeli representatives visited.

He said the graffiti and vandalism would not change the town's push to honor its Jewish origins.
