Monsoon rains have intensified across the country, throwing life out of gear in many cities.
The heavy to moderate rains lashed many cities from Karachi to Khyber and Gilgit-Baltistan, causing rivers and canals to overflow, inundating low-lying areas.
Light to heavy rains continued intermittently in various parts of Karachi on Wednesday, while in Lahore, low-lying areas were inundated by torrential rain, which started early morning.
Around 107mm of rain was recorded on Airport Road in Lahore.
Thunderstorms also occurred in many Punjab cities, including Lahore, Chichawatni, Sahiwal, Sialkot and Toba Tek Singh.
The water level in nullah Lai has risen to a dangerous level after night-long heavy rains lashed Islamabad and Rawalpindi.
Rescue teams continued their search for a father and daughter who were swept away in a rainwater drain in Rawalpindi.
According to the National Disaster Management Authority (NDMA), at least 245 people have died in rain and floods across the country since June 26, including 113 children.
