Lahore recorded 8.4 inches of rain in the 24 hours up to 8am local time on Tuesday
The heaviest rains in 38 years have turned roads into virtual rivers in the eastern Pakistani city of Lahore, stranding motorists and leaving at least six people dead, an official said on Tuesday.
Roof collapses killed at least four people and two others were electrocuted in rain-related incidents, said Jam Sajjad Hussain, spokesman for the Rescue 1122 service.
"Rescue officials using boats saved several persons in the outskirts of Lahore who were stranded in water," Hussain said.
Motorists said journeys that normally took five minutes were taking up to two hours because of flooded roads.
"Whatever road you go on, it is filled with water. We are extremely distressed," motorcyclist Ahmed Shahzad said.
Lahore recorded 8.4 inches of rain in the 24 hours up to 8am local time on Tuesday, the heaviest in 38 years, Pakistan's chief meteorologist Muhammad Riaz told Reuters.
He said a monsoon system would bring continued heavy rains for the next 24 to 48 hours.
