At least seven people were killed and several others injured in Pakistan's Karachi city in separate rain-related incidents.

After weeks of extremely hot weather, the residents of Karachi on Monday found solace when the first monsoon rain in the ongoing summer season hit the port city of over 20 million people, but at the same time the unfortunate incidents of electrocution, roof collapse and uprooting of trees and billboards claimed seven lives, reports Xinhua news agency.

According to the Pakistan Meteorological Department (PMD), rainfall up to 43 mm was recorded in the city, and it wreaked havoc in the areas where it was coupled with heavy winds.

Rescue teams said that the rainwater inundated several low-lying areas of the city, creating trouble for the residents.

Road traffic was also disrupted in several areas after rainwater submerged highways and other roads.

Electric poles also uprooted in several areas of the city, resulting in hours-long suspension of electricity supply.

The provincial disaster management authority of Sindh province, where Karachi is located, issued a warning of urban flooding in parts of the city and other areas.

The authority said heavy rainfall is expected in the province due to the monsoon and the residents and concerned departments of the urban areas should remain alert and take necessary precautionary measures during the forecast periods to avert any unfortunate incident.

The PMD forecast more rains on the same pattern in the city for the next two days.  (IANS)
