The signing of the petition via e-mail was launched by the vice president of the Croatian House that promotes Croatian culture and the country's relations with the United States, Danica Ramljak.
The petition has so far been signed by more than 200 people from the United States, England, Switzerland and France,Ramljak told Hina.
A similar campaign was launched in the southern Croatian city of Split on Thursday, urging the Croatian government not to allow the transfer of Jovic to The Hague after the International Criminal Tribunal for the former Yugoslavia (ICTY), which accused Jovic of contempt of court, on Wednesday issued a warrant for his arrest as he failed to appear before the tribunal to enter a plea.
On 9 September this year, the ICTY issued an indictment against Jovic charging him with publishing in the Slobodna Dalmacija daily the identity and testimony of a protected witness at the trial of Bosnian Croat commander Tihomir Blaskic in March 1998. Jovic published the testimony in the daily in November and December 2000, revealing the identity of the protected witness.
