On 12 April 1993 the Bosnian Serbs told the UNHCR representatives that they would attack the town of Srebrenica within two days unless the Bosniaks surrendered and they did. The same day, Serbs attacked Srebrenica's elementary school, killing 62 Bosniak children and wounding 152 others. There is some confusion about the final number of the dead. No formal investigation was conducted as far as Sead Bekrić's evidence to the ICTY indicates. The memorial at the site refers to the commemoration of between 70 and 100 victims.
