On March 26, a convoy moving logistic supplies for the United States-led coalition came under attack in the southern Iraqi province of Babylon.

The supply convoy was reportedly targeted with an improvised explosive device. No casualties were reported as a result of the attack.

An armed group known as the International Resistance claimed responsibility for the attack. The shadowy group is one of several pro-Iran formations that emerged in Iraq after the assassination of Abu Mahdi al-Muhandis, Deputy-Commander of Iraq’s Popular Mobilization Units, and Commander of Iran’s Quds Force, Qassim Soleimani, by the U.S. more than three years ago.

In a statement, the group said that the supply convoy was “damaged” as a result of the attack, without providing further details.

This was the eighth of the U.S.-led coalition to come under attack in Iraq this year. The International Resistance was behind six of the previous attacks.

The attack came following a heated confrontation between Iranian-backed forces and the U.S.-led coalition in neighboring Syria. The confrontation broke out on March 23 when a pro-Iran Iraqi armed group attacked a coalition base near the city of al-Hasakah with a suicide drone. A U.S. contractor and at least seven Iranian-backed fighters were killed during the confrontation.

The recent attacks in Syria and Iraq were all a part of a covert military campaign by Iran and its allies that is meant to expel the U.S. from both countries.
