ISLAMABAD: Pakistan on Monday accused India of violating the Indus Waters Treaty (IWT) by sending a flood warning through diplomatic channels instead of the treaty’s official mechanism, saying the move was a “serious violation of international law.”

The statement came a day after the Indian High Commission in Islamabad warned of high flood levels in the River Tawi in Indian-administered Kashmir, despite New Delhi announcing in April that it had suspended the decades-old treaty.

“On 24 August 2025, India communicated flood warnings through diplomatic channels, rather than through the Indus Waters Commission as required under the Indus Waters Treaty,” the Foreign Office said, adding that India’s declaration to hold the treaty in abeyance could have “significant negative consequences for peace and stability in South Asia.”

The River Tawi, which joins Pakistan’s Chenab River, runs through the border districts of Gujrat and Sialkot.

Following the Indian alert, the Provincial Disaster Management Authority (PDMA) in Punjab issued a flood warning, directing district administrations to activate monitoring and early warning systems.
