House Republicans launched another new attack on Democrat Jon Ossoff, this time targeting his support for President Barack Obama's Iran deal.

“Terrorists in our shopping centers, jihadists in our streets. And Jon Ossoff supports the dangerous deal allowing Iran billions,” the narrator intones. Watch it here:

The National Republican Congressional Committee’s ad ends with an image of Ossoff with House Minority Leader Nancy Pelosi and Vermont Sen. Bernie Sanders.

Ossoff supports the Iran deal and has said he will vote against any efforts in Congress to undermine it. As a congressional aide, he drafted a resolution demanding the inspection of Iran's nuclear facilities.

In his campaign website, Ossoff said he will "push strongly for strict enforcement and uncompromising monitoring of Iran’s compliance" with the deal.

The dark imagery of the ads were reminiscent of a series of similar attacks against other Democrats running in conservative-leaning districts. They all shared fuzzy video of terrorists and sharp language about impending threats.

There was this negative spot targeting Minnesota Rep. Rick Nolan as "dangerously liberal," and this one assailing Staci Appel as "dangerously wrong for Iowa" in her failed 2014 bid. A third slammed then-U.S. Rep. Dan Maffei, who was defeated in 2014 by Republican John Katko, as a lawmaker who "puts us at risk."
