(CNN) -- Last month's deadly quake in South Asia will cost Pakistan more than $5 billion -- more than twice the amount pledged so far, two international agencies have found in a joint report.Islamabad "will need approximately $5.2 billion to effectively implement a relief, recovery and reconstruction strategy," a comprehensive needs assessment put together by the Asian Development Bank and the World Bank said.The figure includes costs of support for victims and of reconstruction.The report said nations and institutions around the world have pledged assistance totaling nearly $2.5 billion.More than 73,000 people in Pakistan died in the 7.6-magnitude quake on October 8, according to Pakistani authorities. India blamed it for another 1,200 deaths in the Indian-controlled portion of Kashmir.The Pakistani government says at least 70,000 people were severely injured.The Asian Development Bank and World Bank's joint report said the earthquake destroyed more than 200,000 housing units and damaged nearly 200,000 others. An estimated 2.8 million people were left without shelter.As of November 11, the Pakistanis had distributed 350,000 tents, 3.2 million blankets, and 3,000 tons of medicine, and established tent villages for displaced people, the assessment said.The World Bank itself approved supplemental financing of $200 million to help the government meet emergency expenditures.Speaking to CNN's Wolf Blitzer on "Late Edition Sunday," Pakistani President Pervez Musharraf said, "I would call the assistance to the relief operation reasonable, reasonably good." "And we are extremely grateful to the world community and the United Nations and Secretary-General Kofi Annan to be projecting our cause. But now we are getting into the reconstruction and the rehabilitation stage."Musharraf said he would appeal for $5 billion in international donations at a November 19 donors reconstruction conference.
