Nearly a week of heavy monsoon rains and flash floods across Pakistan have killed at least 46 people and injured dozens, officials say. The government announced the death toll on Monday and said the fatalities were caused by several days of abnormally strong downpours.

Torrential rain triggered flash floods that tore through Pakistan’s northwestern Swat Valley over the weekend, killing at least 32 people and laying bare gaps in disaster preparedness in a region once ravaged by Taliban.

The fatalities caused by abnormally strong downpours since Tuesday include 22 in Khyber Pakhtunkhwa, 13 in eastern Punjab province, seven in southern Sindh, and four in southwestern Balochistan, the National Disaster Management Authority and provincial emergency officials said.
