India's External Affairs Ministry said the Indus Water Treaty will be suspended after an attack in Kashmir left over two dozen dead.

At least 26 people were killed and 17 others wounded when gunmen opened fire on tourists in Indian-controlled Kashmir, the worst assault in years targeting civilians in a restive region that has seen an anti-India rebellion for more than three decades.
