Kabul, Afghanistan CNN  — 

Flash flooding in northern Afghanistan killed at least 26 people in northern Afghanistan and rescue workers fear the toll may rise, officials said Monday.

Eight hours of relentless rainfall that began Sunday led to the flooding in several districts of Sar-e-Pol province, said Faizullah Sadat, provincial director of Afghanistan Disaster Management Authority (ANDMA).

More than 100 people are missing, most of them members of a wedding party that was deluged, he said.
