First-Ever US Airstrikes in Nigeria: Christmas Day Tomahawk Strikes on Sokoto

What Happened

On December 25-26, 2025, the United States conducted its first-ever military strikes on Nigerian soil, firing over a dozen Tomahawk cruise missiles from the USS Paul Ignatius — a Navy destroyer stationed in the Gulf of Guinea — at targets in Sokoto State, northwestern Nigeria. The Pentagon stated the strikes targeted camps of the Islamic State Sahel Province (ISSP), the primary ISIS affiliate operating across the Sahel region.

President Trump announced the strikes publicly, framing them as a long-overdue response to an "existential threat" to Christianity in Nigeria. A Nigerian government spokesperson confirmed the strikes targeted "ISIS, Lakurawa and bandits."

Unexploded Ordnance in Villages

At least four Tomahawk warheads failed to explode and fell short of their targets, landing in the villages of Offa, Zugurma, and Jabo. These unexploded missiles created an immediate and ongoing hazard for civilian populations in these communities. The US military has not publicly addressed the failed ordnance or any remediation efforts.

Disputed Intelligence

Multiple analysts and local community members challenged the intelligence basis for the strikes. Responsible Statecraft reported that locals in the targeted areas described "no history of ISIS" presence. CSIS and the Council on Foreign Relations published analyses questioning why the US struck Sokoto specifically, noting that the dynamics of armed groups in northwestern Nigeria — including Lakurawa, bandits, and ISSP — are far more complex than the simple "ISIS camps" narrative presented by the White House.

Trump's framing of the strikes as defending Nigerian Christians was also questioned, as Sokoto is a predominantly Muslim state and the armed groups operating there primarily threaten local Muslim communities.

Legal Analysis

The legal basis for the Nigeria strikes is deeply contested on multiple levels:

Domestic legal authority: The 2001 Authorization for Use of Military Force (AUMF) authorizes force against organizations responsible for the September 11 attacks. Whether it extends to ISSP in Nigeria — an ISIS affiliate operating thousands of miles from al-Qaeda's historical base — is legally questionable. Members of Congress, including Representatives Sara Jacobs and Jason Crow, demanded immediate Pentagon briefings on the legal authority for the strikes.

International law — use of force: Under the UN Charter, the use of armed force against another state's territory is prohibited absent Security Council authorization or self-defense against an armed attack. Nigeria is a sovereign ally, not a hostile state. While the Nigerian government reportedly consented, the nature and scope of that consent — and whether it was obtained before or after the strikes — remains unclear.

Rome Statute jurisdiction: Nigeria is a party to the Rome Statute. Any crimes committed on Nigerian soil by US forces could theoretically fall under ICC jurisdiction, including the crime of aggression (Article 8bis) if the strikes were not adequately authorized under international law.

Civilian protection: The failure of at least four Tomahawk warheads to explode, with the debris landing in civilian villages, raises questions about precautions taken to minimize civilian harm and the choice of weapons platform.

Why This Is Classified Severe

This incident receives a severe severity classification because:

• Unprecedented military action: These were the first-ever US airstrikes on Nigerian soil, establishing a dangerous precedent for unilateral military strikes in sovereign African nations.
• Disputed intelligence basis: Local communities and independent analysts questioned whether ISIS was actually present in the targeted areas, undermining the stated justification.
• Unexploded ordnance in civilian areas: Four failed warheads landed in villages, creating direct hazards for civilian populations.
• Contested legal authority: Neither the 2001 AUMF nor self-defense doctrine clearly authorize Tomahawk strikes in Nigeria.
• Sovereignty implications: Firing cruise missiles at a sovereign ally without clear prior consent and transparent legal authority sets a deeply concerning precedent.

International Law Violations

The following international law provisions are implicated:

1. UN Charter Article 2(4) (Prohibition on Use of Force): Firing cruise missiles at a sovereign nation's territory requires clear legal justification. The basis for these strikes remains disputed.
2. UN Charter Article 51 (Self-Defense): The US was not responding to an armed attack by Nigeria or from Nigerian territory against the United States. The self-defense rationale is tenuous.
3. Rome Statute Article 8bis (Crime of Aggression): If the strikes lacked adequate international legal authority, they may constitute an act of aggression — the use of armed force against the sovereignty of another state.
4. IHL Principle of Distinction: The disputed intelligence about whether ISIS was actually present in the targeted areas raises questions about whether legitimate military objectives were struck.
5. IHL Principle of Precaution: The failure of four Tomahawk warheads to explode and their landing in civilian villages demonstrates inadequate precautions to minimize civilian risk.
