I highly, highly doubt the numbers for WW2 are even remotely accurate. There is no source in the article.

Quickly searching online reveals at least 48 dead mostly American and/or English journalists, although quite a few deaths cannot be considered war crimes even today - being aboard a bomber makes you a valid target I believe.

Besides, where’s the number of killed axis journalists? Surely in Hiroshima there were a few dozen journalists, don’t you think?
