Discussions between Bangladesh and India relating to sharing of Teesta waters is being discussed behind the scene, Foreign Minister AH Mahmood Ali said today.

In the purview of Teesta deal not being inked during Narendra Modi's visit, the minister urged all "to have patience for a concrete outcome".

"Diplomacy does not take place publicly, rather it happens behind the scene," Minister Ali told reporters in a press briefing held at his office a day ahead of the maiden visit of the Indian prime minister.

Expectations were running high that some key agreements would be inked during Modi's visit that would include the long-standing understanding over sharing of Teesta waters and the land boundary deal.

But few days ago, India has made it clear that Teesta deal will not be on the cards for Bangladesh.
