Jeremy Bowen touches on this in his latest article for the BBC.
Getting information from Gaza is difficult. It is a lethal warzone. At least 181 journalists and media workers have been killed since the war started, almost all Palestinians in Gaza, according to the Committee to Protect Journalists. Israel won't let international news teams into Gaza.
Since the best way to check controversial and difficult stories is first hand, that means the fog of war, always hard to penetrate, is as thick as I have ever experienced in a lifetime of war reporting.
It is clear that Israel wants it to be that way. A few days into the war I was part of a convoy of journalists escorted by the army into the border communities that Hamas had attacked, while rescue workers were recovering the bodies of Israelis from smoking ruins of their homes, and Israeli paratroopers were still clearing buildings with bursts of gunfire.
Israel wanted us to see what Hamas had done. The conclusion has to be that it does not want foreign reporters to see what it is doing in Gaza.
