Pakistan ? Torrential rains deluged Karachi, a southern port city, collapsing mud homes, snapping power lines and killing 228 people, officials said Sunday.

Karachi residents angry after a night without electricity to run fans or air conditioners in the sweltering summer heat staged street protests, Karachi Mayor Mustafa Kamal said.

The casualty figures from Saturday’s storms rose after 185 more bodies were counted in the city morgue, said Sardar Ahmed, health minister for Sindh province. Initially, the mayor said 43 people were killed.

Most of the deaths were caused by collapsing homes but at least 20 were electrocuted by snapping power lines, Ahmed said.

Anwar Kazmi, an official at the Edhi Foundation, which runs the morgue, said many of the victims came from a cluster of villages with mud houses and other flimsy structures on Karachi’s eastern outskirts.
