An intense heat wave killed more than 180 people at the weekend in Pakistan's southern city of Karachi, officials said on Monday, as the electricity grid crashed during the first days of the Muslim holy month of Ramadan.

The outages hit large portions of Pakistan's financial heart, which is home to 20 million people. Residents lit bonfires in protest.
