At least 14 people were killed in Pakistan after powerful windstorms struck Sindh over the weekend, while India’s financial capital of Mumbai faced flash flooding and travel chaos as monsoon rains arrived early following weeks of punishing heat in the region.

The deaths in Pakistan occurred as strong winds and thunderstorms swept through southern districts of the Sindh province on Saturday evening, causing homes to collapse and trees to fall.

Several deaths were also reported in the Punjab province as extreme wind gusts toppled trees, downed electricity poles, and damaged infrastructure, including in the capital Islamabad. Officials said several of the victims were children. Over 100 were reported injured.

The storms, described as “particularly destructive” by officials, followed a period of extreme heat when temperatures soared above 45C.
