Muslims living in a small town in northern Germany were shocked to find someone had bricked up the entrance to their mosque during the night.
Those gathering for prayers last Friday in the town of Parchim found the door to the mosque jammed with concrete breeze blocks, on which crude flyers with anti-Muslim slogans had been stuck.
"You call yourselves believers. We call you invaders," one of the flyers read.
Another contained lines from a poem recited in public by Recep Tayyip Erdogan, the Turkish president: "The mosques are our barracks, the minarets our bayonets, the faithful our soldiers".
Police are investigating the incident, which is suspected to be the work of a far-Right group.
