The chairman of the House Intelligence Committee, in an interview with Fox News, implicated Iran in the bombing of Israeli tourists in Bulgaria and said the U.S. should take Israel at its word that they will retaliate. 

"I believe the Israelis when they say there will be retaliation for this attack," Rep. Mike Rogers, R-Mich., told Fox News. "I don't think we should do anything but take them at their word." 

Israeli Prime Minister Benjamin Netanyahu and other top officials in his government have vowed to strike back, blaming Iran for the attack that killed five Israelis. Iran has denied responsibility, but Rogers said there are "indicators" it is tied to Iran -- and he believes the bomber had help to execute the operation. 

"It was targeted against Jews specifically. We believe it was Hezbollah who was purposefully targeting ... likely to be inspired by some command from Iran," Rogers told Fox News Thursday night.
