Where was Abraham's Ur?

Gen 11:31 Terah took Abram his son and Lot the son of Haran, his grandson, and Sarai his daughter-in-law, his son Abram's wife, and they went forth together from Ur of the Chaldeans ( Ur [Light] of the ones of Kesad [Clod breaker] ) to go into the land of Canaan, but when they came to Haran, they settled there. (ESV)

No argument about it, Haran is in Turkey.  If Terah and his family were going to Canaan from the UR of the Southern Mesotomia  why would he go the opposite direction?

Could the city of Abraham's birth be Urfa?
