Given the recent pattern of attempted attacks by individuals linked to Tehran, Rogers said he believes the regime is seizing the moment -- effectively throwing gasoline on the flames. 

"You worry that Iran is starting to escalate these types of activities," Rogers said. "It shows how brazen they have become and how aggressive they have become ... so Iran is certainly ramping it up, and obviously that's a problem." 

Rogers told Fox News he believes the bomber had outside help from a "logistical system," and the path will lead back "through Hezbollah and likely I think into Iran." 

He said this "fits their profile." 

Officials have said the bomber was carrying a fake driver's license from Michigan. Rogers suggested that detail could bear clues. 

"It could have been absolutely, just something they came upon to use or could have been more significant to try to send a message," Rogers said. "We're going to find that out in a few days and I will tell you nobody knows today."
