SOFIA, Bulgaria (AP) — Israeli Prime Minister Benjamin Netanyahu is calling Iran the "most potent force of militant Islam" and is warning Europe of possible Iranian attacks on its soil.

Speaking to reporters Thursday after talks with his Bulgarian counterpart, Netanyahu said radical Islam is a threat to the world, and that Israel has recently revealed a number of Iranian plots to carry out attacks on European soil.

Netanyahu arrived in Bulgaria's Black Sea city of Varna for Friday's meeting of the Craiova Forum, which includes the prime ministers of Bulgaria, Greece and Romania, as well as the president of Serbia.

Ahead of his trip, Netanyahu said he wants to strengthen ties with these countries and "change the hostile and hypocritical approach of the European Union" toward peace in the Mideast.
