Asked whether he was aware that Croatian weapons bought by Saudi Arabia were turning up in Syria, Kihalic said: “There is nothing more for us to check, as the [export] document says their ministry of defense or police forces [in Saudi Arabia] will use it [the weapon] and that they won’t resell it or export it.”

Human rights groups dispute Kihalic’s view. Patrick Wilcken, an arms researcher for Amnesty International, said that Croatia is obliged to take measures to prevent both weapons from being diverted to another country, and from being used to commit serious human rights violations. Given the mounting evidence of the systematic diversion of arms from Saudi Arabia to armed groups in Syria, Croatia’s failure to take due diligence to prevent further diversion could result in a breach of the EU Common Position and the Arms Trade Treaty.

Bodil Valero, a Green Party member of the European Parliament from Sweden and the parliament’s rapporteur on arms, criticized Croatia and called on the EU to tighten its grip on its members’ arms exports.

“Croatia has used Saudi Arabia as it is not allowed to export to Syria, and it ends up in the hands of ISIS and the Kurds,” she told BIRN and OCCRP. “We have to do much more.”
