On 16 June 2021, Frontex launched a new operation in Serbia. 44 standing corps officers from 14 countries helped detect criminal activities:

• Trafficking in human beings;
• Document fraud;
• Smuggling of stolen vehicles, illegal drugs, weapons, and excise goods;
• Potential terrorist threats.

“Joint Operation Serbia ‒ Land 2021” is taking place at Serbia’s border to Bulgaria in order to counter the increasing number of illegal border crossings observed in recent years.
