Sweden has been hit by nearly 200 bombings during 2025. Meanwhile, customs authorities have seized over 42,000 explosive items during the first six months of the year – almost double compared to the entire previous year.

Police now see a clear shift where stolen goods from construction sites have been replaced by smuggled war materiel and illegal fireworks from the Balkans and Eastern Europe.

The bombings continue to shake Sweden. So far this year, the country has been hit by nearly 200 completed or failed bombing attacks, according to information obtained by Stampen-owned Göteborgs-Posten.

But the patterns are changing. Where it was previously most common for criminals to use explosives stolen from construction sites, police now see a new and alarming trend.

— During the summer and autumn, we have primarily seen detonations with hand grenades and with homemade explosive devices, says Malin Nygren, head of the Swedish police’s national bomb data center.

Smuggling increases dramatically

Behind the change lies a sharp increase in smuggling. In many cases, it involves hand grenades or illegal fireworks being brought into the country from the Balkans or Eastern Europe.

The numbers speak for themselves: During the first half of 2025, customs seized over 42,000 explosive items. This is a record figure that almost doubles the just over 24,000 seizures made during all of 2024.

Martin Norell, expert at the Swedish Customs Service (Tullverket), shares the police’s concern about the development.

— I don’t feel that the situation is very bright in Sweden right now, he says.

Children manipulated to carry out the attacks

Behind the grim statistics lies a particularly dark reality: It is often children who are manipulated by criminal networks to carry out the bombing and arson attacks. The young perpetrators have in several cases been seriously injured when handling explosives and flammable liquids, and at least one death has occurred.

Many of the bombings have been carried out with smuggled hand grenades used for both revenge and extortion, and on several occasions unexploded hand grenades have been found in residential areas – or at or near preschools.

Dan Windt, operational coordinator at the Swedish police’s national operations center, urges parents to be vigilant.

— Parents and other important adults need to continue being present in children’s lives both physically and digitally. Ask many questions and ask for help. Contact the social services in your municipality if the child is contacted by criminals, or call the police at an early stage if you suspect that your child is about to commit a crime, so we can prevent it together.
