There are 2 areas where Neelum river is the border between AJK and Indian Occupied Kashmir.
First one is Teetwal sector. We may have missed the flags when Teetwal sector started. This border patch ends on the slopes of a mountain on other side of river and its all jungle. Even the posts were not visible.
Second place is Keran sector which starts just after Athmuqam and continues till Lawat. Here i captured flags at both locations:
Between Athmuqam and Keran where border starts on river Neelum.
