But we are told, again and again, that ALL journalists, reporters, TV crews, including stringers presumably, are not allowed inside Gaza. Are we not?

I don't want to bang on about it, but the journalists in Gaza would be 'stringers'. There could be different rules as to the use of 'stringers' between Sky and BBC. An assumption.

As to the studio interviews and such, as far as BBC is concerned, Raffi Berg rules the roost. No surprises. BBC is a zionist entity, or zionist apologist or whatever.
