After the Belgrade massacre where nine children and a school guard were killed, a series of bomb threats was made to primary and secondary schools in Serbia.

Authorities in the capital city registered a number of warnings for detonating devices places in school premises.

The Ministry of Education confirmed that 78 primary schools and 37 secondary schools in Belgrade had received emails of bomb attacks, only two weeks after the shocking tragedy of “Vladislav Ribnikar” primary school.

Police sent specialized groups on the field to investigate these threats, while students and teachers were evacuated.

There has been no data of actual bombs being found in schools and police has yet to make a clear statement.

The first ever massacre in the modern history of Serbia happened two weeks ago, when a 13-year-old boy shot at pupils using his father’s guns.

Only a day after the tragedy, a 21-year-old opened fire on residents in the town of Mladenovac, killing eight and injuring some 14 others.

The two violent episodes sparked outrage and debate over the culture of violence that has been present in Serbian society since the wars that broke up Yugoslavia.

President Aleksandar Vučić announced an initiative for handing in weapons, and citizens have handed over 15 thousand unregistered weapons in exchange for amnesty from criminal offenses.
