Serbian police say they have arrested several drug and arms traffickers, as well as a fugitive suspect in this year's clashes between police and armed groups in Macedonia.

Interior Minister Nebojsa Stefanovic said Friday the arrests were made in separate police actions throughout the country. He said police confiscated drugs and automatic weapons in the operation.

The Balkan region is a well-known smuggling gate toward Western Europe. Stefanovic says one of the suspects headed a heroin smuggling ring stretching from Turkey to Western Europe, while four others were trafficking arms from Serbia to France.

He says the Macedonia suspect was detained on the border with Kosovo on an international warrant over clashes in northern Macedonia that killed 22 people earlier this year.
