Operation Hawkeye Strike: Massive US Bombing Campaign in Syria

A large-scale US retaliatory bombing campaign in Syria following the deaths of three Americans near Palmyra. The scale of the operation — hundreds of munitions across dozens of targets in populated desert regions — raises serious questions about proportionality and civilian protection under international humanitarian law.

Beginning December 19, 2025, the US launched Operation Hawkeye Strike — a massive retaliatory bombing campaign across Syria following the killing of two US soldiers and a civilian interpreter near Palmyra. Over 100 munitions were dropped on 70+ targets in the first wave alone, with follow-up strikes continuing into February 2026. Airwars and other monitors have documented civilian casualties.

Executive summary

What this record documents

  • On December 19, 2025, the US launched Operation Hawkeye Strike with over 100 munitions on 70+ ISIS targets across Syria, using A-10s, F-16s, Apache helicopters, and HIMARS guided artillery, with support from Jordanian F-16s.
  • The operation was retaliatory — responding to the December 13 Palmyra attack that killed two US soldiers (Sgt. Edgar Torres-Tovar and Sgt. William Howard of the Iowa National Guard) and a civilian interpreter (Ayad Mansoor Sakat).
  • A second wave on January 10, 2026 struck 35+ targets with 90+ precision munitions. Additional strikes continued through February 2026.
  • Airwars has documented civilian harm incidents from the campaign. The strikes targeted areas in Homs, Raqqa, and Deir ez-Zor provinces — regions with civilian populations.
  • The legal basis under international law is disputed. Just Security published analysis questioning whether the scope and scale of retaliation was proportionate and whether ongoing strikes qualify as self-defense.

Analysis

Reporting, legal context, and impact

What Happened

On December 19, 2025, the United States launched Operation Hawkeye Strike, a massive retaliatory bombing campaign across Syria. The operation was a direct response to an ambush near the ancient city of Palmyra on December 13, 2025, in which a Syrian police officer — suspected of Islamic State affiliation — killed two US soldiers from the Iowa National Guard and an American civilian interpreter.

The first wave alone involved over 100 munitions dropped on more than 70 targets across central and eastern Syria. The US deployed A-10 Thunderbolt ground attack aircraft, F-16 fighter jets, Apache attack helicopters, and HIMARS precision-guided rocket artillery. Jordanian Air Force F-16s provided support. Targets included command centers, weapons depots, training facilities, drone operations sites, and logistical hubs spanning three Syrian provinces: Homs (including the Jabal al-Amour area near Palmyra), the Ma'adan desert in rural Raqqa, and the al-Hammad desert in Deir ez-Zor.

Continuing Strikes

The campaign did not end with the initial barrage. On January 10, 2026, a second major wave struck 35+ targets using 90+ precision munitions. On January 16, a targeted strike killed Bilal Hasan al-Jasim, described as a senior leader of an al-Qaeda-affiliated group tied to the Palmyra ambush. Between January 27 and February 2, 2026, CENTCOM conducted five additional strikes destroying ISIS communications, logistics, and weapons facilities with 50 precision munitions.

The total scale of Operation Hawkeye Strike — hundreds of munitions across more than 100 targets over several months — makes it one of the largest US bombing campaigns in Syria since the height of the anti-ISIS campaign.

Legal Analysis

The legal questions surrounding Operation Hawkeye Strike are substantial, as analyzed by Just Security and other legal scholars.

Proportionality: The initial strikes — 100+ munitions on 70+ targets in response to an attack that killed three Americans — raise questions about whether the scale of retaliation was proportionate under international humanitarian law. While the US framed the strikes as degrading ISIS operational capacity, the sheer volume of ordnance delivered across three provinces in a single operation warrants scrutiny.

Self-defense and sovereignty: The strikes were conducted in Syrian territory without the explicit consent of Syria's new government. While the US claims authority under the 2001 Authorization for Use of Military Force (AUMF) and the inherent right of self-defense, legal scholars have questioned whether open-ended retaliatory campaigns in a sovereign state meet the international law requirements of necessity and proportionality in self-defense.

Civilian protection: Airwars has documented civilian harm incidents from the campaign. While the targeted areas are described as desert locations, the provinces of Homs, Raqqa, and Deir ez-Zor all contain civilian populations. The obligation to take feasible precautions to minimize civilian harm applies regardless of the remoteness of a target.

Why This Is Classified Severe

This incident receives a severe severity classification because:

  • Scale: Hundreds of munitions dropped across 100+ targets in multiple Syrian provinces over weeks. This is a major military campaign, not a targeted strike.
  • Civilian harm: Airwars has documented civilian deaths from the strikes, with the full extent still under investigation.
  • Legal ambiguity: The operation's legal basis under both domestic and international law is contested. The scope of retaliation may exceed what is permissible under self-defense doctrine.
  • Sovereignty concerns: Strikes within Syrian sovereign territory without clear host-nation consent raise fundamental questions about the lawfulness of the use of force.
  • Precedent: The scale of retaliatory bombing — 100+ munitions for an ambush that killed three — sets a concerning precedent for disproportionate military responses.

International Law Violations

The following international law provisions are implicated:

  1. IHL Principle of Proportionality: The scale of the campaign — hundreds of munitions across months — relative to the triggering attack requires careful proportionality analysis.
  2. IHL Principle of Distinction: Strikes across populated provinces require rigorous distinction between combatants and civilians. Documented civilian casualties suggest potential failures.
  3. IHL Obligation of Precaution: The duty to take all feasible precautions to minimize civilian harm during military operations.
  4. Geneva Conventions Article 51, Protocol I: Protection of civilians against the effects of hostilities, including the prohibition on indiscriminate attacks.
  5. UN Charter Article 2(4): The ongoing use of force in Syrian territory without clear authorization or consent of the Syrian government.
