Israeli Prime Minister Benjamin Netanyahu said Sunday that Israeli intelligence had gathered "rock solid evidence" that Hezbollah and Iran were behind last week's bombing of a bus with tourists in Bulgaria.
"We know with absolute certainty, without a shred of doubt, that this was a Hezbollah operation," Netanyahu said on Fox News.
In a separate interview that aired shortly after on CBS News, Netanyahu said Israel would do "whatever is necessary" to protect its citizens, and warned "there has to be a price extracted" from terrorist networks and their state sponsors.
The Israeli prime minister also said the recent terrorist attacks should force the international community to intensify pressure on Iran to halt its nuclear weapons program.
"You want these people to have atomic bombs? I think this is a reminder, this wave of terrorism attacks, that the world's most dangerous regime must not be allowed to have the world's most dangerous weapons," Netanyahu said.
"They're basically thumbing their nose at the international community," he added.
The Israeli leader also discussed rapidly deteriorating conditions in Syria, where he predicted the "regime will go."
"I don't think it's sustainable," Netanyahu said.
He also reiterated that Israel would consider entering the country to contain weapons of mass destruction to make sure they did not fall into the hands of rogue states or terror networks. And while Netanyahu indicated he would like American support for such an operation, he also said Israel would be willing to act alone.
"I think this is a common concern, we have to see if there is a common action to address that concern," Netanyahu said. "In any case, we certainly don't want to be exposed to chemical weapons falling into the hands of Hezbollah or other terrorist groups."
The prime minister was asked about presidential candidate Mitt Romney's upcoming trip to the country, but repeatedly deferred from comment or appearing to choose sides in the American political battle.
"You're far to wise a journalist to think I'm going to get into your field of American politics," Netanyahu joked to Fox's Chris Wallace. "I will receive Mitt Romney with the same openness that I received another presidential candidate, then-Sen.

Netanyahu did seem to caution the Obama administration, however, during a moment where he was discussing the similarities between Republican, Democratic, and Israeli foreign policy toward Iran. The prime minister said his country had received "bipartisan support" on the issue of Iran.
"But the jury is out on all of this," Netanyahu said. "The real question is not stated policy, but actual results on the ground."
