At least 11 labourers were killed and five others injured on Wednesday when a wall collapsed during heavy monsoon rains on the outskirts of Pakistan's capital.
Pakistan receives heavy -- often destructive -- rains during its annual monsoon season, which is crucial for agriculture and water supplies.
The men were crushed to death as they slept in tents next to the bridge that they were constructing in Islamabad.
"So far the dead bodies of 11 labourers have been recovered while five others have been injured in the incident," administration official Nehel Hafeez told AFP.
"The incident took place around 0120 GMT this morning after last night's heavy rains," she added.
Police also confirmed the casualties.
Last year, Pakistan was lashed by unprecedented monsoon rains over the summer that put a third of the country underwater, damaging two million homes and killing more than 1,700 people.
At least 60 people have died in weather-related incidents across Pakistan since the end of June.
