There have been a couple of recent (post-October) studies into BBC coverage, the issue I raise concerning the language used in the title is consistent with its use of language elsewhere. For example, Israelis are “killed” and Palestinians “die”.

"About 700 people have been killed in Israel since Hamas launched its attack on Saturday, with a further 500 having died in Gaza in retaliatory air strikes."
"Some 1200 people have been killed in Israel, while more than 1000 have died in retaliatory air strikes on Gaza."
"More than 700 people have been killed in Israel since Saturday and over 500 people have died in Gaza."

[…] the openDemocracy analysis found that the phrases “murder”, “murderous”, “mass murder”, “brutal murder” and “merciless murder” were used a total of 52 times by [BBC] journalists to refer to Israeli deaths – but never in relation to Palestinian deaths.

When I read this sort of coverage on a daily basis, I see these patterns repeated again and again, it’s a subtle reframing that many don’t notice but editors (and headline writers) at the BBC will be very aware of how they are using language. Space is not an excuse to remove the perpetrator from the picture regardless of how obvious that perpetrator might be, it is disingenuous.

Study shows BBC ‘bias’ in reporting on Palestinian and Israeli deaths - The National

I’ve seen articles that said 1,200 Israelis killed by Hamas and then the next sentence said 32,000 Palestinians killed…but didn’t say by Israel.

The juxtaposition of those two sentences may lead some people to think that Hamas killed those tens of thousands.

I agree with you regarding headlines, but the article text itself should make it very clear that the vast majority of civilians killed in this conflict were killed by the Israeli Occupation Forces.
