ROME, Oct. 3—Pope Paul issued an appeal today for aid to the “800,000 exhausted, sick and starving children” from East Pakistan who are now living in refugee camps.

The Pontiff, addressing crowds in St. Peter's Square, invited the churches of the world to join him in making next Sunday a day of prayer and fasting in the children's behalf.

“It is necessary to wake up the sense of humanity in the world to save the lives of countless human beings on the verge of death,” the Pope said.
