war crime
What to know
A war crime is a serious violation of the laws and customs of war, collectively known as international humanitarian law (IHL). These rules—most notably codified in the 1949 Geneva Conventions and their Additional Protocols—seek to minimize the harm of armed conflict by protecting civilians, prisoners of war, and other non-combatants, as well as by restricting the methods and means of warfare. The United Nations classifies war crimes within its broader category of “atrocity crimes,” alongside genocide and crimes against humanity.
Under US federal law, grave breaches of IHL are prosecuted under the War Crimes Act of 1996, which criminalizes certain serious violations of the Geneva Conventions. The scope of this act was expanded in 2023 under President Joe Biden to strengthen accountability for people involved in war crimes abroad who are found in the US.
According to the United Nations, hospitals, schools, civilians, humanitarian workers, cultural and religious sites, and safe corridors for aid delivery are all protected under international humanitarian law. Examples of war crimes include intentional attacks on civilians, collective punishment, the use of prohibited weapons (such as chemical or biological agents), torture, taking hostages, and forcible displacement of populations. Genocide, while often linked in public discourse, is recognized as a separate international crime under its own legal convention.
The process of proving war crimes is complex and often lengthy. Cases require extensive documentation, credible witness testimony, and secure access to evidence—all of which are difficult to obtain during or after conflict. Accusations of war crimes remain allegations until proven through legal proceedings in national courts or international processes such as the International Criminal Court (ICC).
This delay can place journalists and researchers in challenging positions when they observe or report on events that appear to meet the legal criteria for war crimes. Until judicial bodies make determinations, journalists play an essential role in documenting, verifying, and contextualizing evidence that may later support accountability efforts. Clear, fact-based reporting—identifying which provisions of IHL might have been violated and explaining their relevance—helps audiences understand both the legal framework and the human consequences when those rules are broken.
Credible international organizations such as the United Nations, Human Rights Watch, and Amnesty International regularly publish verified reports on conduct in armed conflicts. These reports, along with documentation from local human rights groups, journalists, and eyewitnesses, are key resources for identifying potential violations. Scholars and legal experts in IHL can further help clarify definitions, applicable statutes, and the evidentiary standards required to prove war crimes.
Social media increasingly serves as an open-source evidence repository for possible war crimes. Many investigative organizations now use digital forensics and geolocation tools to verify such content. However, journalists should apply rigorous verification methods—confirming the authenticity, location, and source credibility of digital materials—to avoid amplifying misinformation. Transparency about a newsroom’s verification process fosters public trust and empowers audiences to identify misleading or manipulated content independently.
To ensure accuracy and minimize harm, it’s crucial to avoid presenting alleged perpetrators’ statements as fact unless supported by credible evidence. Any counterclaims should be described within the context of available verification and without implying equivalence between unverified assertions and documented findings. This standard applies across all coverage, including headlines, social posts, and push alerts. Using clear, active language—such as “killed” instead of “died”—provides audiences with a precise understanding of events and holds individuals accountable.
Consistent reliance on verified sources and international human rights documentation is key to maintaining factual integrity in coverage. This emphasis on credible sources instills audience confidence in the information it receives.
In current global reporting, journalists covering Israel and Palestine face particular scrutiny. Reports published in 2024 by the United Nations, Human Rights Watch, and Amnesty International alleged that Israeli military operations in Gaza involved actions meeting the legal definition of war crimes, including attacks on healthcare facilities, mass displacement, and deliberate obstruction of aid. The Israeli government has denied these allegations. That same year, the International Criminal Court issued arrest warrants for senior Hamas commanders on charges including murder and sexual violence, and for Israeli officials, including Prime Minister Benjamin Netanyahu, on charges such as starvation of civilians and persecution as methods of warfare. Netanyahu and Israeli leaders publicly rejected the ICC’s jurisdiction and criticized its actions.
When reporting on these or any allegations and denials, exercise caution in repeating unverified claims. Always identify the credibility of your sources, indicate whether independent verification has been conducted, and provide context to prevent the spread of misinformation. Grounding coverage in evidence, law, and transparency upholds both journalistic standards and the principles of international humanitarian accountability.
