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, at targets in Sokoto State, northwestern Nigeria. A US defense official told The New York Times the strikes involved over a dozen Tomahawk cruise missiles fired from the USS Paul Ignatius, a Navy destroyer in the Gulf of Guinea; Nigeria's information minister, Mohammed Idris Malagi, said 16 GPS-guided munitions were fired from MQ-9 Reaper drones. The two accounts have not been reconciled publicly. 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." The US said the strikes were approved by and coordinated with the Nigerian government, and the Nigerian Armed Forces said they were jointly conducted with the government's approval.

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. Nigeria's information minister said the debris caused no civilian casualties; a former state official told the BBC that about five structures in Offa were destroyed, with some injuries but no deaths.

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. Consent of the territorial state is a recognised basis for the use of force on its territory, and both the US and the Nigerian Armed Forces stated that the strikes were approved by and coordinated with the Nigerian government. On the available record, the strikes therefore do not breach Article 2(4).

Rome Statute: Nigeria is a party to the Rome Statute, so the ICC has territorial jurisdiction over war crimes committed on Nigerian soil. But the government's consent defeats any aggression premise, and no civilian deaths have been documented, so no Rome Statute crime is in play on the current record.

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 Graded Major

The major grade names "unauthorized military deployments"; the live question here is domestic legal authority, not international law:

• Unprecedented military action: These were the first-ever US airstrikes on Nigerian soil.
• 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 domestic legal authority: The 2001 AUMF does not clearly cover ISSP or Lakurawa in Nigeria, and Congress was not consulted in advance.

International Law Provisions Considered

1. UN Charter Article 2(4) (Prohibition on Use of Force): Not breached on the available record, because Nigeria approved the strikes.
2. UN Charter Article 51 (Self-Defense): Not needed as a justification where the territorial state consents.
3. 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.
4. IHL Principle of Precaution: The failure of four warheads to explode and their landing in civilian villages raises questions about the precautions taken to minimize civilian risk.
