The two attacked boys were admitted to the local hospital and underwent operations due to injuries they suffered when they were stabbed.
The protesters today marched through the downtown Pula bearing banners with slogans "Stop Violence" "No to Fascism" and enlarged copies of release forms which the victims got when they left the hospital.
The marchers, whose rally was organised by some 70 associations, were handing out leaflets reading 'Diversity Makes Us Special'.
The two Pula citizens were attacked by the three men at about 04:00 hrs 14 November. The attackers stabbed them.
The first attacker, identified as Darko Basaric from the eastern city of Osijek, was charged with a murder attempt, and is detained in custody for one month. The second attacker, Mauro Tromboni, was charged with counts of brawl, and was released from custody pending the start of trial. The third attacker was acquitted.
