Flash floods and storms killed at least 18 people after ravaging several provinces of Afghanistan over the past five days, an official confirmed Wednesday.

Many Afghans die every year in torrential heavy rains, particularly in impoverished rural areas where poorly built homes are at risk of collapse.

Deputy minister for disaster management Sharafuddin Muslim confirmed that the latest floods ravaged the provinces of Faryab and Parwan, as well as various other regions.

In a video statement, Muslim said "18 to 20 people have been killed across 10 provinces" and that more than 100 houses were also destroyed.

Two people remain missing while 30 others have been injured.

Relief teams have been dispatched to the affected areas with tents and food, and the authorities are distributing money to families of those killed, Muslim highlighted.

Since the Taliban movement took control of the country in August last year, foreign-funded aid and disaster relief schemes have dramatically decreased.

This year's flooding also came as the country observed Eid Al-Fitr holiday after the fasting month of Ramadan ended on Saturday in Afghanistan.
