Pakistan floods aftermath: Destruction highlights impact of climate change
Pakistani officials have started evacuating tens of thousands of people after neighbouring India released water from overflowing dams and swollen rivers into low-lying border regions.
The move on Tuesday came a day after New Delhi alerted Islamabad about possible cross-border flooding, the first public diplomatic contact between the two countries since a four-day war in May.
The latest flood alert and evacuation drive by Pakistan comes as heavy monsoon rains continue to batter both South Asian countries, with at least 800 people reported killed in Pakistan since late June.
