State-run Pakistan Television immediately said that retaliatory attacks were underway targeting "multiple locations in India."

Pakistan’s army said it struck several Indian military sites early Saturday in retaliation for India’s missile strikes on airbases, a significant escalation in the conflict between the two nuclear-armed neighbors.

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.
