ISLAMABAD: President Asif Ali Zardari said on Tuesday Pakistan faced a “new threat in the form of the weaponization of water,” accusing India of violating the Indus Waters Treaty during his address to the World Summit for Social Development in Doha. The 1960 treaty, brokered by the World Bank, divides the waters of the Indus River system between India and Pakistan and has long been regarded as one of the world’s most durable water-sharing agreements. It allocates the three western rivers — Indus, Jhelum and Chenab — to Pakistan, and the eastern rivers — Ravi, Beas and Sutlej — to India.
