The attacks, carried out on May 2 and 3, 1995 in retaliation for a Croatian army offensive dubbed Operation Flash which crushed a Serb armed insurgency in Western Slavonia on May 1, left seven people killed and 205 wounded, including 49 seriously.
The city authorities erected a monument in 2007 to commemorate the attacks.
The head of the Zagreb association of Homeland War civilian victims, Marija Vrazic, said that the families of the people killed or wounded never received any compensation from the state and urged the authorities to address this issue.
