Israeli Prime Minister Benjamin Netanyahu called Iran "the strongest militant of Islamic power" and warned Europe of possible attacks.
On Thursday, after meeting a Bulgarian colleague, journalists say radical Islam is a threat to the world. He added that Israel has just come out more Iranian plan attacks in Europe.
Netanyahu traveled to Bulgaria with Bulgaria, Prime Ministers of Greece and Romania, and Friday's talks with President of Serbia. Before traveling, he said he wanted to strengthen cooperation with these countries "to change the hostile and hypocritical approach of the European Union" peace in the Middle East.
