The top U.S. general overseeing the Middle East said on March 12 that an Iran-backed terror group was likely responsible for the rocket attack that killed U.S. troops in Iraq a day earlier.
McKenzie said the military is still investigating the attack.
However, he strongly suggested that Iran-backed terror group Kataib Hezbollah, which the United States has blamed for previous rocket attacks in the region, was behind the March 11 incident.
“I will note that the Iranian proxy group Kataib Hezbollah is the only group known to have previously conducted an indirect fire attack of this scale against coalition forces in Iraq,” McKenzie said.
A U.S. military spokesperson for the anti-ISIS coalition in Iraq confirmed that three personnel were killed in the Camp Taji attack, while other officials told media outlets that two Americans and a Briton died.
Iraqi forces wrote that they found a rocket-armed truck several miles from the camp.
Secretary of State Mike Pompeo wrote that he spoke to his British counterpart after the attack.
U.S. military officials blamed Kataib Hezbollah for a rocket attack in December 2019 that killed a U.S. contractor and injured several troops. In response, the United States conducted strikes on Kataib Hezbollah in Iraq, before Iran-aligned militia groups attempted to storm the U.S. Embassy in Iraq. Kataib Hezbollah was deemed a foreign terrorist organization by the State Department in 2019.
The United States then approved an airstrike to kill Iranian Gen. Qassem Soleimani in early January. Top U.S. officials said Soleimani was planning attacks on U.S. assets and had killed hundreds of Americans over the years.
Iran then launched a barrage of about two dozen rockets at two Iraqi military bases holding troops, causing minor injuries to more than 100 service members, most of whom have since returned to work. President Donald Trump later announced more sanctions on Tehran.
