To clarify the question of journalists in Gaza, quite simply, international journalists are banned by Israel from entering Gaza. A very few who have been granted permits must remain embedded with the IDF, are not allowed any contact with Palestinians and are subject to having their reports vetted by the IDF. The reports we do get are mostly from Palestinian "citizen journalists" or are from social media. I could speculate that the IDF have certain things they'd rather we didn't see. Al Jazeera reports that over 90 journalists and their staff have been killed. Other outlets, including the Guardian article, put the number at 63. With the exception of a handful of Israeli and a couple of Lebanese journalists, they were all Palestinians. Jeremy Bowen is the chief BBC mouthpiece in this conflict - see his comment in the article about the difficulty of accurate reporting when he's obliged to report only from Israel.
