Here's the article. The headline now says:

Reuters and AP journalists killed in Gaza strike were not 'a target,' an Israeli military spokesperson says

According to the "last updated" field, the article was last updated 8 hours before OP made this post on Lemmy. It's possible the headline was changed, but this may also have been the original headline -- I can't find any record of the previous headline on Reuters, including Internet Archive. (Edit: the headline was changed; see comment.)

Seeing as this is "Fediverse vs Disinformation," I think posters have a duty to verify the web page actually reads the way they are claiming at the time they post, or else provide context that the headline has changed.
