Prime Minister Binyamin Netanyahu on Sunday repeated his assertion that Iran and its terrorist proxy Hizbullah are behind the terror attack in Burgas, Bulgaria, Wednesday.

Netanyahu said his assertion that Hizbullah is behind the attack last week that killed five Israeli tourists is based on “rock solid” intelligence and on its resemblance to other recent attempted attacks across the world, included one in Cyprus last week.

“It’s the same modus operandi,” he said on Fox News Sunday. “It’s them and we know it.”

Netanyahu called the Iran government “the world’s most dangerous regime.”

The prime minister will meet Republican presidential contender Mitt Romney this month as part of the Romney’s seven-day international trip to England, Israel and Poland.

Netanyahu said that he would express to Romney the same thoughts that he expressed to President Barack Obama when he was running for the White House in 2008 – his citizens’ desire for peace and their concerns about Iran having nuclear weapons.

Netanyahu said he and President Obama in principle about keeping Iran from having such weapons, but he declined to go further. “You’re not going to draw me into your politics,” he said. 

“Just imagine what would happened if this regime got a hold of nuclear weapons,” Netanyahu said on CBS’s “Face the Nation.” He repeated that Israel has “unquestionable, fully-substantiated intelligence” that the Burgas attack “was done by Hizbullah backed by Iran.”

CBS‘s Bob Schieffer also tried to elicit a statement from Netanyahu regarding the race between Romney and Obama. “Oh God, I’m just not going to go that way, Bob,” Netanyahu said, and explained that he has enough of his domestic politics to deal with without becoming involved in that of the United States.
