Pınarbaşı (Kurdish: Aynserê,[2] Syriac: Ayn-Sare)[nb 1] is a village in the İdil District of Şırnak Province in Turkey.

[1] It is the largest village in the district.

[1] Ayn-Sare (today called Pınarbaşı) was historically inhabited by Syriac Orthodox Assyrians.

[5] In 1914, the village was inhabited by many Kurdish families and 150 Assyrians in 15 families, according to the Assyro-Chaldean delegation to the Paris Peace Conference.

[6] Amidst the Sayfo, a number of Assyrians fled to Azakh after having been warned by a Kurdish woman that their Kurdish neighbours were conspiring to massacre them, whilst those who did not believe her and remained at Ayn-Sare were killed.
