A car belonging to a journalist who was the first to raise issues about a BBC documentary on Gaza was vandalised on Saturday.

David Collier was in Tel Aviv when the vehicle at his London home was doused with a “chemical substance” that stripped its paint.

Police are treating the incident as “racially aggravated”, with specialist hate crime officers reviewing evidence.

Mr Collier, 59, frequently posts about the Israel-Hamas conflict on social media sites.

Earlier this year, he revealed that the narrator in the BBC documentary Gaza: How To Survive a War Zone, was the son of a Hamas government minister – a connection which was not disclosed in the film.

The BBC went on to pull the hour-long documentary from its iPlayer streaming platform and said it “had not been informed” beforehand of the link between Abdullah Al-Yazouri, the 14-year-old narrator, and Ayman Alyazouri, his father and a senior figure in Hamas.

However, the incident sparked a slew of complaints and the BBC has since launched an investigation to decide whether staff should be sacked over alleged failings.

Mr Collier, who has nearly 233,000 followers on X, claims he now receives death threats on a “daily basis”.

Last month, he said he was particularly concerned about a message which stated that the sender knew where he lived.

Shortly afterwards, his car was keyed on the driver’s side. Mr Collier, a father-of-two, went on to report the incident to the police.
