"Wire scares our people but does absolutely nothing to stop anybody," one of the organisers said at the Against Wire, For Humane Europe rally.

"Such a sad wire will not stop the people who were willing to travel thousands of kilometres," Luka Juri explained.

While there were more protesters on the Croatian side of the fence demanding that Prime Minister Miro Cerar remove the wire, both sides were unanimous that there was no need for the razor wire.

"The wire is a moral mistake. The last time a wire fence was erected in such dimensions was around Ljubljana in 1942. We cannot allow our government to do in 2015 the same thing the fascist occupying forces did then," Juri added.

Protesters played a symbolic game of volleyball over the fence to show respect for the people on the other side of the border. One of the players noted that wires were never set up by free countries but by those that did not want people to get out.

"It is something completely different from what they're telling us. Now we don't know on which side we are - on the free or on the occupied."

Later on protesters rallied at the Dragonja border crossing, where some 200 people came from the Slovenian side of the fence, including from Bela Krajina in the south east of the country.

Organisers read what they described as the "Dragonja Declaration", in which they again urged the Slovenian government to remove "the morally and ecologically contentious wire".
