in all affected areas and had rescued thousands of people. Prime Minister Yousaf Raza Gillani visited the province and directed the Pakistan Navy to help evacuate the flood victims. By early August, more than 352,291 people have been rescued. By the end of August, the Relief Web Financial Tracking service indicated that worldwide donations for humanitarian assistance had come to $687 million, with a further $324 million promised in uncommitted pledges. Since the early stages of the emergency, the United Nations had warned of a potential "second wave of death" that would result from post-flood disease and food shortages, stating that 3.5 million children were at risk of death if they did not get assistance, including due to cholera. UN spokesperson Maurizio Giuliano stated that "an already colossal disaster [was] getting worse and requiring an even more colossal response", referring to the relief operations as "a marathon at sprint pace" and acknowledging shortcomings in the response insofar as the needs were outpacing available resources also due to endless rains. He indicated that the floods had a worse impact than several other recent natural disasters combined, and that they were the worst natural disaster in United Nations history. According to UNOCHA, by 2011, a total of $2,653,281,105 had been raised in humanitarian support, the largest amount by the US (25.8%), followed by private individuals and organisations (13.4%) and Japan (11.3%). With need for substantial support to repair infrastructure, US Secretary of State Hillary Clinton suggested that the Pakistani government enlarge its tax base by asking the wealthy citizens of Pakistan to contribute more for their country; by that time both the US and the EU each had contributed about US$450 million, €395 million for the relief effort. Response by national governments Afghanistan finance minister Omar Zakhilwal handed a cheque worth US$1 million (45 million Afghanis) to Pakistani ambassador Mohammad Sadiq at the end of a press conference in Afghan capital Kabul. Algeria donated €100,000 to Pakistan. Argentina sent drinkable water. Australia announced to contribute and said that it will double its aid program to Pakistan to $66.5 million in official development assistance in 2010–2011, as well as committing two C17 Globemaster aircraft to deliver emergency supplies and to assist relief efforts and deploying a medical task force consisting of up to 180 personnel and more than 33 tonnes of equipment. Austria donated €5.6 million to Pakistan. Azerbaijan gave US$2 million financial
