I've seen more reported about the BBC than other media outlets. I don't know if that is because they are worse than the others, or just because we expect better of them. Anyway, here goes:
(November 2024): More than 100 BBC staff accuse broadcaster of Israel bias in Gaza coverage, also reported in Al Jazeera and Middle East Eye. And here is the letter
(June 2025): The Centre for Media Monitoring (CfMM) has put out a report on BBC bias, BBC On Gaza-Israel: One Story, Double Standards with a link to the report here. Two articles in Middle East Eye: BBC coverage of Israel's war on Gaza 'systematically biased against Palestinians' and War on Gaza: How the BBC sanitises Israel's genocide
(June 2025): A film, "Gaza: Medics Under Fire" was produced for the BBC, but they sat on it for months, and are now not going to show it. Apparently it is being made available to the producers, Basement Films, to show.
This article, Discontent Deepens Among Guardian Staff Over Palestine ‘Double Standard’ discusses its topic at length, including the Guardian's rejection of an article by Susan Abulhawa, now available here, and she is interviewed here, and writes on the same theme here.
This article concerns an article which was "nixed" from the Guardian at the last minute. It is now available here, A Surge in Suppression, by Dylan Saba.
