Three regions of Pakistan are reportedly witnessing a 20% drop in flow of rivers as compared to last year. Flow in Pakistan's Punjab region stands at 1,10,500 cusecs, down from 1,30,800 cusecs on the same date last year, while in Sindh, water flow reduced to 1,33,000 cusecs from 1,70,000 cusecs. This comes after India put Indus Waters Treaty in abeyance.
