Heat waves in Pakistan’s city of Karachi and neighbouring communities of southern Sindh province have killed at least 122 people.

Health official, Saeed Mangnejo, said on Sunday that 114 people have died in Karachi and eight others equally passed away in three districts of Sindh.

He said that the provincial government has imposed a state of emergency and has cancelled leave applications by doctors and other medical staff.

He said the government is increasing stocks of medical supplies to assist the sick.

Seemin Jamali, the head of the emergency department at state-run Jinnah Hospital, said more than 100 people have died at the hospital.

“They all died of heat stroke,” she said.

According to Aljazeera, the southern port city of Karachi saw temperatures rise to 45 degrees Celsius on Saturday, just short of an all-time high in the city of 47 C in June 1979.

A large number of the deceased were old people.

Officials said most of the deaths occurred Saturday evening.

A few weeks earlier massive heat waves also killed hundreds in India
