Serbian police have arrested 10 people suspected of arms-trafficking and confiscated a large quantity of weapons, including rocket launchers and automatic guns.

Interior Minister Nebojsa Stefanovic said Wednesday that the arrests took place in northern Serbia. He said an investigation is taking place to determine whether the weapons were to be sold, and if so where.

Stefanovic says the cache included explosives, more than 100 hand grenades, anti-tank mines, two rocket-launchers, a machine gun, automatic and semi-automatic guns, as well as ammunition.

Arms-smuggling has flourished in the Balkans following the wars of the 1990s when many weapons were left behind and later sold or distributed illegally. Some of the weapons used in last year's terror attacks in Paris originated in the Balkans.
