CHARIKAR, Afghanistan (AP) – The death toll from two days of heavy flooding in northern and eastern Afghanistan rose to at least 150 on Thursday, with scores more injured as rescue crews searched for survivors beneath the mud and rubble of collapsed houses, officials said.

Heavy rains, compounded by mudslides, often threaten remote areas of Afghanistan, where infrastructure is poor. Summer often brings heavy rainfall and flooding to the country’s north and east.

Flash floods inundated the city of Charikar in northern Parwan province starting Tuesday night. The Health Ministry said on Wednesday that the local hospital was partially destroyed and many injured were being transferred to the capital Kabul.

Powerful flood waters in the mountainous province dislocated thousands of large rocks that caused major injuries and destroyed entire homes, burying people under the rubble, officials said. Several excavators reached the area and were digging for those stuck beneath the rubble.

Mohammad Qasim Haidari, Afghanistan’s deputy minister for disaster management, said the casualty toll may rise as rescue teams and volunteers were still working to locate people buried under destroyed houses.

The head of the provincial hospital, Abdul Qasim Sangin, said every 30 minutes to an hour a corpse was being delivered to the hospital. He said several children were among the dead and some of the injured are in critical condition.

A popular vacation destination for many Afghans, Charikar was the location of many of Parwan province’s casualties and also suffered much property destruction in the flooding.

Hamid Agha, 50, a Charikar resident, said he lost all his family members to the flood except two sons who are truck drivers and were delivering goods in another province.

Mr. Agha was able to pull himself out of the rising waters but was unable to save his family. “Out of 11 family members in the house only I am alive,” he said. “We buried six bodies but four others are still missing.”

A group of people was seen Thursday digging out their belongings, including blankets, clothes, mattresses and pillows, from houses partially or completely filled with mud.

Afghan President Ashraf Ghani in a videoconference promised full support to those who lost homes and family members over the past two days. A group of Afghan businessmen delivered food and cash to families in Parwan.

Ahmad Tameem Azimi, spokesman of the disaster management ministry, said flooding blocked highways to eastern and northern provinces. “Along with rescuing people we are working to open the highways back to traffic,” he said Wednesday. More than 2,000 houses were destroyed in Parwan and over 1,000 people were displaced, he said.

Mr. Azimi said hundred of acres of agricultural land have been destroyed, with the heavy rain wiping out all the crops in 13 provinces. Houses and roads were destroyed in northern Kapisa, Panjshir and eastern Paktia provinces, Mr. Azimi said.

In neighboring Pakistan—which struggles every year to cope with the annual monsoon deluge—heavy rains have lashed many parts of the country this week.

The southern port city of Karachi, also the nation’s financial capital, was hardest hit. Pakistani navy boats on Thursday evacuated hundreds of people from flooded areas of the city. At least 99 people have died in rain-related incidents across Pakistan since Sunday, the country’s national disaster management agency said.
