Tensions between India and Pakistan remain high days after Delhi launched airstrikes at its neighbor, sparking tit-for-tat military action from both sides and widespread confusion as competing claims and disinformation spread online.

India has threatened before, in other moments of rising tensions, to pull out of the Indus Waters Treaty, which both countries signed in 1960. If India follows through this time, it could restrict the flow of water that is used for most of Pakistan’s crop irrigation and human consumption. Agriculture represents one-fourth of the country’s economy.

The neighbors have been in conflict over the disputed border region since their independence and partition in 1947.
