Would experienced birdwatchers please help to confirm the identity of these gulls?

Yes, I believe they are, judging from the pale grey colour of the mantle and upperwing, and gentle head structure. Of course Yellow-legged Gull in this region actually have pinkish legs. I also remember that the amount of white on wing-tip is also an indicator, but I do not remember the details.
Nice photos.
