Due to snowfalls and heavy rains, flights from and to the airport of Kabul, through which most of the aid arrives, were cancelled, the spokesman said.
More snowfalls and low temperatures are expected for the coming days, which will have a negative impact on millions of people from this central Asian nation, the spokesman stressed.
In late December, the UN Security Council unanimously adopted a resolution that sought to speed up the delivery of humanitarian aid in Afghanistan.
However, the humanitarian partners of this multilateral organization are running a race against the clock now to provide aid and supplies in line with the commitments to expand operations, the UN official website reports.
For its part, the International Organization for Migration expressed great concern over the millions of internally displaced people in Afghanistan, a very vulnerable population that urgently needs adequate shelters to face winter.
After the untimely withdrawal of US forces, after some 20 years of military occupation, and the return to power of the Taliban movement in August 2021, the crisis in Afghanistan worsened, and millions of people were displaced or fled the country.
