KARACHI, Pakistan (AP) — Monsoon rains inundated much of Pakistan, leaving large parts of the southern city of Karachi underwater and causing at least 17 deaths as of Sunday.

Rescue official Anwar Kazmi said seven people died from electrocution and three people died after a roof collapsed in Karachi. The downpour and flooding began overnight, with authorities reporting more than 180 millimeters (7 inches) of rain in the port city.

Police officer Idrees Khosa said five people died in a flash flood and another two were electrocuted in Punjab province, which also saw heavy rains.

Pakistan struggles to cope with the yearly monsoon, which runs from July to September and causes flooding across South Asia.
