At least 55 more reported killed on Tuesday. Flash floods swept away 45 members of three families who were shifting from Bote Bogha to some safer location in Bhakkar. The ill-fated families in small boats were making an attempt to leave the area devastated by unprecedented floods when their boats capsized in swirling water. Soon after the incident, Army and rescue teams rushed to the site and started rescue operation. However, not a single body was found.

Four persons including were taken away by raging floods while one minor was killed when lightning struck him at Kot area. Meanwhile, relief work for some 3.2 million people has been delayed by swamped roads, washed-out bridges and downed communication lines.

Water levels were so high in large tracts of Kot Addu and the nearby Layyah, that only treetops and uppermost floors of some buildings were visible. Meanwhile, the floodwater has entered Dadu District in neighbouring Sindh, submerging over 50 villages and destroying thousands of acres of cotton and other crops. The district administration has imposed emergency in view of floods and established 40 rescue centres. Floodwater also entered Daira Deen Panah City and its rural suburbs in Muzaffargarh District on Tuesday after over 900,000 cusecs water current, that passed through Taunsa Barrage on Monday, broke Abbas Wala Spur.
