Thank you Hertz. Someway round the impasse must be found, and your suggestion is stimulating. My only trouble with it is that, in terms of the lead para.it is lengthy, and the lead para.is supposed, unless I am mistaken, to deal with essentials. What about:-

Adjacent to Hebron is the populous/densely populated Jewish township of Kiryat Arba, a separate municipality, but within five minutes walking distance ([citation] ) from the Cave of the Patriarchs in Hebron?

It's for me, a matter of concision and technically proper language, basically. Let me know what you think. Regards
