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.
