Monsoon floods across Pakistan have killed at least 58 people and affected tens of thousands of others, and officials say there is more rain to come.
"At least 58 people have died, more than 30 others were injured and 66,000 were affected by rain and flooding in Pakistan since July 31," Brigadier Mirza Kamran Zia, operations chief of the National Disaster Management Authority (NDMA), told reporters on Monday.
Zia said floods were receding and people were returning to their homes, but he warned that more rain than usual was expected this month and next.
NDMA chief Major General Muhammad Saeed Aleem said the recurring flooding was the result of global climate change.
"Unexpected rains are global climatic change phenomena, but we can prepare and plan ahead to mitigate the disaster," Aleem said.
