Tens of thousands of Serbs have joined protests against gun violence in the capital Belgrade and another city after two mass shootings last week.
EDnews informs via foreign media that seventeen people died in the shootings on Wednesday and Thursday, including eight children in a primary school.
The protesters are demanding that top government officials resign, and want newspapers and TV stations that they say promote violence to be shut down.
Serbia's President, Aleksandar Vucic, condemned the protests.
He accused the opposition of capitalising on a national tragedy to promote their own interests. He said he was ready to test his party's popularity at a snap vote.
"I will continue to work and I will never back down before the street and the mob... Whether it will be a reshuffle of the government or an election, we shall see," he said on TV.
The next parliamentary elections are set to take place in 2026.
Police were stationed near all of Belgrade's schools as they restarted classes on Monday. The government is planning to recruit more officers to be stationed at schools.
Crowds marched through the centre of the city behind a banner that read "Serbia against violence".
"We are here because we can't wait any longer. We've waited too long, we've been silent too long, we've turned our heads too long," Marina Vidojevic, a schoolteacher, told the crowd, as quoted by AFP news agency.
"We want safe schools, streets, villages and cities for all children."
