It said that Potezica, 64, was rushed to a hospital after the crash some days ago near the coastal town of Sousse, but died today. No other details were given.
In November 2015, gunmen in Libya crashed into a convoy of vehicles taking Potezica to neighboring Tunisia and then kidnapped two Serbian embassy employees. He escaped unharmed along with his wife and two sons.
The two Serb hostages died in a US airstrike on an Islamic State camp in February 2016 in western Libya that killed dozens. Serb officials had questioned why the Americans did not appear to know that foreign captives were at the site.
