WarClaim: A Dataset for Fake News on 2023 Israel–Hamas war

The 2023 Israel-Hamas conflict began in early October 2023, and as the conflict progressed, various instances of fake news began spreading worldwide. Fake news appeared on different platforms and was in multiple languages. For the scientific study of fake News, claims, and propagation, we contribute the first publicly available dataset of claims, fake social media posts, and fact-checked articles on the 2023 Israel-Hamas war. The WarClaim data is collected from 131 fact-checking organisations in 40 languages. We explain the data collection approach and source of the dataset. The WarClaim dataset is enriched by providing the information used by trained journalists specialising in fact-checking organisations. The dataset presented here can be utilised in various research endeavours, such as developing machine learning models and conducting exploratory studies. The dataset will be available on Github1.
