The first 10 weeks of the Israel-Gaza offensive have been the deadliest recorded for journalists, with the most journalists killed in a single year in one location, the US-based Committee to Protect Journalists (CPJ) has said.

According to Reuters, most of the journalists and media workers killed in the war — 61 out of 68 — were Palestinian. The report said it was “particularly concerned about an apparent pattern of targeting of journalists and their families by the Israeli military.”

A spokesperson for Israel’s military has said the forces don’t target journalists.

The group, a nonprofit organization that promotes press freedom worldwide, said it was further investigating the circumstances of all journalist deaths. It said such efforts in Gaza were hampered by widespread destruction and by the killing of journalists’ family members, who typically serve as sources for investigators looking into how the journalists died.
