Historic monsoon rains and flooding across Pakistan have affected more than 30 million people over the last few weeks, the country's climate change minister said on Thursday (August 25), calling the situation a "climate-induced humanitarian disaster of epic proportions."

Pakistan has called on the international community to help as it struggles to cope with the aftermath of torrential rains that have triggered massive floods, killing more than 900 people.
