The stranded and homeless families in Dir Upper, Chitral and other hilly areas of the worst-hit Malakand Division badly need shelter, warm clothes, food items and medical facilities as winter sets in, senior provincial minister InayatUllah Khan said.
"The provincial government would welcome immediate assistance of world community and international relief agencies," he said.
He, however, said that such an international help must be on crash basis and in practical shape rather than mere offers, commitments and assurances.
The deceased include 225 from Khyber Pakhtunkhwa (KP), 30 in northwestern tribal regions and 10 in Gilgit-Baltistan.
The minister said that though some international bodies have contacted the KP government but the victims direly needed a prompt help and relief.
He said that the dropping level of mercury and increasing snowfalls would aggravate the situation.
