In a statement, the Ministry of Foreign Affairs (MoFA) expressed its sincere condolences and sympathy with the friendly people of Afghanistan, and to the families of the victims, as well as its wishes for a speedy recovery for all the injured.

Flash floods from unusually heavy seasonal rain in Afghanistan have killed more than 300 people and destroyed over 1,000 houses, the UN food agency said on Saturday.

The World Food Programme (WFP) said it was distributing fortified biscuits to the survivors of one of the many floods that hit Afghanistan over the last few weeks, mostly the northern province of Baghlan, which bore the brunt of the deluges on Friday.

In neighbouring Takhar province, state-owned media outlets reported the floods killed at least 20 people.

Videos posted on social media showed dozens of people gathered on Saturday behind the hospital in Baghlan looking for their loved ones. An official tells them that they should start digging graves while their staff are busy preparing bodies for burial.
