From a story on politico.com by Steven Overly headlined “Hamas uses social media to incite fear, researchers find”:

Social media was a key tool of Hamas militants as they waged their brutal attack on Israel over the weekend, according to an online misinformation expert: the group leaned on platforms with loose rules against terrorism propaganda and misinformation to sow fear and misinformation.

“A big part of the strategy of inciting terror is not just the attack … but also depends on their ability to incite fear in especially online spaces,” said Graham Brookie, senior director of the Atlantic Council’s Digital Forensic Research Lab, which has been tracking the attack’s online presence as it evolves.
