Chachran Sharif , Pakistan ( CNN ) -- Imam Baksh used two cots as shelter over his head and a third to shield him from the drenched earth . The 80-year-old man was among thousands in Chachran Sharif who could see his home submerged under water -- about half of the Pakistani town looked more like a lake than a community of people . Even the mosque was under water and people were using boats to rescue their cows , goats and sheep , dragging the terrified animals onto dry -- or at least dryer -- land . Chachran Sharif , in Pakistan 's Punjab province , is one of many villages , towns and cities across Pakistan reeling from torrential monsoon rain and flooding that authorities now say have affected 12 million people and killed as many as 1,500 . Pakistan 's disaster management authority estimated that 650,000 houses have been damaged or destroyed . By comparison , the earthquake of 2005 affected 3.2 million people and damaged or destroyed 611,000 homes . And no relief is in sight as the bloated Indus River overflows its banks and more rain continues to fall . Pakistan 's Meteorological Department issued an alert for the southern province of Sindh , far away from the northern Swat Valley , where the crisis began . `` Pakistan has been hit by the worst flood of its history , '' said Prime Minister Yousuf Raza Gilani in a televised speech Friday . `` As I speak , the flood is still engulfing new areas and adding to the scale of devastation . '' Gilani said a true assessment of the loss to life and infrastructure can be determined only after the water recedes . He appealed to the international community and to Pakistanis living abroad to dig deep into their pockets . Relief agencies said donations are needed urgently to alleviate suffering . Patrick Fuller has worked for the International Red Cross for 15 years and been involved in other disasters . Still , he said Friday he was shocked by what he saw . `` These people need help desperately and the world needs to wake up , '' Fuller told CNN . People ca n't go back to their homes . They are living in a precarious situation . '' He said there has been a conspicuous absence of aid in some areas , despite efforts by the Red Cross and other international aid groups . Parts of the Swat Valley remain inaccessible by road ; helicopters provide the only way in or out for people , food , clean water or medicine . At Chakdara , south of the valley 's largest city , Mingora , people queued for more than four hours to cross a rickety temporary suspension bridge above swirling brown water . With the main highway crossing destroyed , people trying to escape were using a decrepit British-built 19th century bridge that was damaged in the rain . Meanwhile , among the suffering , anger grew at the government for perceived lack of action . Pakistanis hurled stinging criticism at President Asif Ali Zardari , who was in England for talks with British Prime Minister David Cameron during the worst of the crisis . Advisor Farahnaz Ispahani said Zardari was simply doing his job as head of state and had ensured the crisis at home was being adequately addressed by the prime minister . In Chachran Sharif , there were few signs of aid for the flood-displaced and frustration mixed with drizzle in the air . `` We elected him , '' one man said about Zardari . `` Where is he ? '' U.S. emergency relief teams were continuing to arrive in Peshawar for distribution by Pakistan 's National Disaster Management Authority , the State Department said Friday . In all , the U.S. Agency for International Development has committed $ 35 million in aid to international organizations and non-governmental organizations , it said .
