I am not very sure, the angle of the photos don't give away the easiest way to identifying it which is the "V" shape on the back.
Little & Red-necked have pretty similar features but with slight differences. I can't really compare the size judging by these photos as there is only one bird. But I think this is a Red-necked for following reasons:
1. Red-necked Stint have proportionately shorter bill and legs than Little
2. Red-necked have longer wings & tail than Little
3. Supercilium & base of bill whitish
4. Crown cap is reddish-brown
5. In breeding, Red-necked Stint's head is entirely reddish-brown, while Little will have paler throat
Was this bird seen in a flock of Red-necked stint?
