For whatever reason, The Guardian cannot bring itself to admit that the Temple Mount is the holiest site in Judaism. Or that it means anything at all to Jews, in fact. From Just Journalism:
The editorial lists the concessions which were allegedly offered, including the issue of sovereignty over The Temple Mount/Haram al-Sharif:
'Haram al-Sharif, the third holiest site in the Muslim world? That, too, is up for grabs. Mr Erekat said he was prepared to consider "creative ways" to solve the problem of Haram al-Sharif or the Temple Mount.'
Therefore, according to The Guardian, any suggestion that the Israelis and Palestinians might agree to somehow share the hotly contested site constitutes a surrendering of 'the third holiest site in the Muslim world'. This is despite the widespread recognition that The Temple Mount/Haram al-Sharif is held to be the most sacred site in Judaism, a fact that is omitted from the editorial.
This emphasis on how any hypothetical sharing would be a thorny issue for Muslims, at the expense of any mention of the significance for Jews, is maintained throughout a series of articles by Middle East editor Ian Black, and associate editor Seamus Milne.
