The inspection is being carried out in accordance with an annual international defence cooperation plan and the Subregional Arms Control Agreement, the head of a Croatian inspection team, Colonel Bosiljko Mijatovic, said.
The Serbian military inspectors were accompanied by an assistant from the Organisation for Security and Cooperation in Europe (OSCE).
Mijatovic said that two more inspections were scheduled for this year and that Croatian Army inspectors would carry out similar checks in Serbia.
The Subregional Arms Control Agreement was signed in Florence in 1996 by Croatia, Bosnia and Herzegovina's two entities -- the Federation of Bosnia and Herzegovina and the Republika Srpska, and the now defunct Federal Republic of Yugoslavia (Serbia and Montenegro), with a view to establishing a military balance between the signatories.
