Nearly 200 U.S. troops have been killed and nearly 1,000 injured by Iranian-made explosives in Iraq, according to new disclosures from a partially declassified report conducted by U.S. Central Command and described by sources to the Washington Free Beacon.

The number of U.S. deaths resulting from Iranian terrorism were revealed for the first time on Wednesday by Sen. Ted Cruz (R., Texas) during a hearing focusing on the Obama administration's failure to prosecute terrorists directly responsible for the deaths of Americans.

At least 196 U.S. service members fighting in Iraq were killed directly as a result of Iranian-made explosively formed penetrators, or EFPs, according to Cruz and congressional sources familiar with Centcom's mostly classified report.

The deaths took place between 2003 and 2011. The Iranian explosive devices wounded another 861 U.S. soldiers, and a total of 1,534 attacks were carried out on U.S. military members over this period, according to sources familiar with the report, which was provided to Cruz's office.

The explosive devices are a "hallmark weapon" of Iran's Quds force, a paramilitary group that operates outside of Iran's borders, according to sources familiar with the report. It has been determined that only Iranian-backed operatives use these weapons in Iraq.

    U.S. military leaders disclosed in testimony before the Senate that Iranian terror activities have claimed the lives of around 500 U.S. soldiers, which accounts for at least 14 percent of all American casualties in Iraq from 2003 to 2011.

    "That blood is on Iran's hands," Cruz said Wednesday afternoon during a hearing on the Obama administration's decision to not prosecute terrorists who have murdered American citizens and troops abroad.
