December 2019 United States airstrikes in Iraq and Syria

Overview

On 29 December 2019, the United States conducted airstrikes against Kata'ib Hezbollah's weapons depots and command centers in Iraq and Syria, reportedly killing at least 25 militiamen and wounding 55 more. The U.S. Department of Defense said the operation was in retaliation for repeated attacks on Iraqi military bases hosting Operation Inherent Resolve (OIR) coalition forces, particularly the 27 December 2019 attack on a Kirkuk airbase that left an American civilian contractor dead. Kata'ib Hezbollah, an extremist Shi'ite militia funded by Iran, denied any responsibility for the attacks.

Significance

On 29 December 2019, U.S. forces struck Kata'ib Hezbollah weapons depots and command centers in Iraq and Syria, killing at least 25 militiamen and wounding 55 more. The Department of Defense framed the operation as a direct response to a pattern of attacks on Iraqi bases hosting Operation Inherent Resolve coalition forces, culminating in a 27 December strike on a Kirkuk airbase that killed an American civilian contractor. The strikes marked a significant escalation in the low-intensity contest between U.S.-led coalition forces and Iranian-backed militias operating in Iraq, drawing Kata'ib Hezbollah — a Shi'ite militia funded by Iran — into sharper focus as a principal actor threatening coalition presence. Kata'ib Hezbollah denied responsibility for the preceding attacks, and the strikes contributed to a rapid deterioration in U.S.-Iran tensions that would intensify in the days that followed.
