Pakistan declared a public holiday in Karachi on Wednesday as the financial capital braced for more rain, after the arrival of the annual monsoon season left at least 7 people dead and caused widespread flooding,

Pakistan has received higher-than-normal monsoon rainfall this year, triggering floods and mudslides that have killed more than 540 people since June 26.

In one of the deadliest incidents, 24 people from one family died in the village of Qadar Nagar when floodwaters swept through their home on the eve of a wedding. The head of the family, Umar Khan, said he survived the floods because he was out of the house at the time. Four of his relatives have yet to be found, he added.
