Instagram has emerged as a significant platform for citizen journalism, enabling individuals to disseminate firsthand information and alternative narratives during armed conflicts. This study examines the role of Instagram in disseminating information about the Palestine–Israel conflict through citizen journalism and explores public responses to such content. A qualitative descriptive approach was employed by combining thematic analysis of Instagram comments with a Systematic Literature Review (SLR). Public comments were collected from selected Instagram posts published by prominent Palestinian citizen journalists, while relevant literature published between 2016 and 2026 was systematically reviewed following the PRISMA framework. The findings indicate that Instagram functions as a strategic medium for documenting humanitarian issues, amplifying Palestinian voices, and fostering global awareness beyond the agenda of mainstream media. Audience responses primarily reflected humanitarian concerns, solidarity, emotional engagement, calls for collective action, and evaluations of information credibility. However, the study also identifies significant challenges, including algorithmic bias, content moderation, shadow banning, and account restrictions, which reduce the visibility of Palestinian narratives and constrain citizen journalism practices. The study contributes to the literature on digital communication by demonstrating how Instagram facilitates citizen journalism in conflict settings while highlighting the importance of journalistic ethics, digital rights protection, and collaboration with professional media organizations to strengthen information credibility and counter misinformation.
