Monsoon-induced flooding has wreaked havoc on both sides of the Himalayan region, which is divided between the two nuclear-armed rivals.
The floods, which hit on September 7, also caused devastating economic losses running into billions of dollars to the area's famed carpet exporters.
The government in PoK issued a resolution calling for the United Nations to intervene, which was passed by the parliament of the territory.
"The government of Pakistan should contact the United Nations and government of India to open the ceasefire line to supply the relief goods to the flood victims for their rehabilitation," the resolution by the 49-member house said.
