 ::::::The report bothers to call them ""contracted"" fieldworkers, which means their non-member status in AI matters. I understand being ""based"" in Gaza as residing there, and 99.9% of the population there is Palestinian, but there is no mention of their nationality in the report. Do you see another reasonable interpretation of the word ""based"" ? We can write ""Gaza-based contracted fieldworkers"", but I find it more awkard.  
 ::::::NGO Monitor doesn't call itself  ""Israeli"", nor does WP article about it claim so. Their mailing address is in Jerusalem, but since it's disputed that Jerusalem is in Israel - we might as well call them a Palestinian NGO. I see nothing wrong with ""Jerusalem-based NGO Monitor""."
