Okay, here why I believe the photo is not
Dianthus anatolicus.
First off, the two photos posted here under
Dianthus anatolicus show markedly different flower form, and though it's not as clear from the photo, it looks like the plant form is different too (loose form and long flower stems, as compared to the tight, bun-forming, tufted character of
D. anatolicus).
Note that the text with the photo at the Gardens In the Woods site states that "The photos of Dianthus anatolicus seem to be conflicted...". This is certainly clear if you google photos that purport to be this species - there is a mix of character between plants like the photo posted by Robert, and ones like this photo. It goes on to say "... but it is generally considered to be white to pale pink, with a darker, contrasting eye and scalloped petals"; this statement does summarize the very mixed Google photos, but it doesn't match the species description.
Here's the species description from eFlora of Pakistan:
http://www.efloras.org/florata...
The petals are described as "subentire to dentate at apex, ebarbulate", in other words, not highly divided/lacinated as in the photo above. Flowers are "white to rose pink" - no dark, contrasting eye (although colour zones and dark centers are characteristics of some other
Dianthus species). It's a small-flowered plant, as suggested in this description (the "limb" of the petals is said to be 3-4mm, that is, the part of the corolla that forms the "petals"), unlike the photo above.
Here's the entry from the Alpine Gardening Society:
http://encyclopaedia.alpinegar...
It says "densely hummock-forming", "leaves to 4.5mm long", unlike many of the loosely formed plants that come up in a google photo search. Also: "Flowers white, 5-7mm across" - again, it's small flowered. Note the comment immediately below in which a contributor notes that plants in horticulture generally have pink flowers (as in Robert's photo) and he speculates that they may be garden hybrids.
Also: "the petals slightly toothed" - not lacinated, as in this photo.
Here are some photos of
Dianthus anatolicus that seem to match the description (and you can find many others, among the imposters):

As for the plant in the photo, I take back the suggestion of it being
D. deltoides - with the lacinated petals and colour zone in the center, and loose form, it looks pretty dead-on for a colour form of
Dianthus gratianopolitanus:
