...so I went and did a little research. It turns out that one of these mosques is a shrine to a certain Imam Asim, a charming fellow that played an important part in the purposeful destruction in the 10/11th centuries of the Buddhist Khotan kingdom that once occupied the area, during which destruction apparently 'there were years of battles where "blood flows like the Oxus", "heads litter the battlefield like stones" until the "infidels" were defeated'. Unsurprisingly this violence also included the razing of countless Buddhist temples in the area.
Thus the Guardian, apparently with a straight face, asks us to mourn the destruction of a shrine to a warlord when said warlord was part of a deliberate and concerted programme of ethnic cleansing and cultural destruction including destruction of the temples of an earlier culture. At this point my irony meter is off the scale.
