Pakistan ordered businesses, schools and public offices in Karachi to shut on Wednesday after torrential monsoon rain left at least 10 people dead in the densely populated port city, with more heavy downpours predicted.

The National Disaster Management Authority (NDMA) said on Wednesday that 11 people were killed in Gilgit-Baltistan in the north and 10 others died in Karachi, Pakistan’s financial hub, where heavy rain triggered electrocutions and house collapses.

Torrential rains continued pouring on dozens of villages in northern Pakistan, triggering flash floods that have wiped out houses and killed hundreds.
