India warned Pakistan of possible cross-border flooding following heavy monsoon rains in South Asia, marking the first public official contact between the two nuclear-armed rivals in months. Pakistan’s Foreign Ministry stated that New Delhi conveyed the information through diplomatic channels rather than the Indus Waters Commission, the permanent mechanism established under the 1960 Indus Waters Treaty mediated by the World Bank. An Indian government official said the warning was issued “for humanitarian reasons” and not under the treaty. There was no immediate comment from New Delhi. This is the first diplomatic contact since May, when India carried out missile strikes inside Pakistan following the killing of 26 tourists in Kashmir in April. Pakistan responded with its own strikes, raising fears of escalation before US President Donald Trump brokered a ceasefire that has held so far.

The warning comes amid monsoon rains causing floods that have killed about 800 people in Pakistan since June 26. Dozens have also died due to floods in the Indian-administered part of divided Kashmir, which both sides claim in full.
