evidence: Sir Creek (/sər ˈkrik/ sər KREEK), originally Ban Ganga,[1] is a 96 km (60 mi) tidal estuary in the uninhabited marshlands of the Indus River Delta on the border between India and Pakistan. The creek flows into the Arabian Sea and separates Gujarat state in India from Sindh province in Pakistan.[2] The long-standing India-Pakistan Sir Creek border dispute stems from the demarcation "from the mouth of Sir Creek to the top of Sir Creek, and from the top of Sir Creek eastward to a point on the line designated on the Western Terminus".[2][3] From this point onward, the boundary is unambiguously fixed as defined by the Tribunal Award of 1968.[4] [...] Sir Creek lies just to the west of the Great Rann of Kutch area of India. On the Indian side, Sir Creek is one of the six main creeks in this area, the others being Vian Wari Creek (Vianbari and Viyanbari), Pir Sanai, Pabevari, Padala (16 km (9.9 mi) southeast from Sir Creek), and easternmost Kori (34 km (21 mi) southeast from Sir Creek).[7][5] All of these creeks are within the undisputed territory of India, except the westernmost creek, Sir Creek, which is claimed by both India and Pakistan. These evershifting creeks exit Indian territory, enter Pakistan, re-enter India, and vice versa, creating a hard-to-patrol, marshy wetland border with no physical barrier or fencing.[5]
