The government announced last night that it would double aid to disaster-hit Pakistan. International Development Secretary Andrew Mitchell said an extra 33million was being offered on top of the 31.3million already pledged to help cope with the effects of floods, reported British Media. Speaking in New York, Mr Mitchell told the UN General Assembly it was "unacceptable" that the international community had not done more, and urged other donors to step up their efforts. Mr Mitchell visited Pakistan on Wednesday before flying to New York to lobby the international community, particularly the G8, to do more to alleviate the humanitarian disaster. He said: "I've come to New York directly from Pakistan, where I saw the dire need for more help. "Yesterday I saw the sheer and shocking magnitude of this catastrophe. It is clear that unless more aid is delivered now, many more people will die from disease and malnutrition. "It is deeply depressing that the international community is only now waking up to the true scale of this disaster. "The UK is already helping more than three million people in flood-affected areas. "This doubling of our aid should now provide water and sanitation to 500,000 people, shelter to 170,000 people, help meet the nutritional needs of 380,000 people and provide enough health services to cover a population of 2.4million people. "I am in New York to urge the rest of the world to follow the example of those countries that have increased their support in recent days. The wealthiest nations, especially those in the G8, have a duty to step up their response dramatically." The extra 33million will only be released when the government is confident it will help the people of Pakistan access desperately needed medicine, food, clean water and shelter. Former prime minister Gordon Brown also called on governments around the world to do more for the flood victims yesterday. He said: "The unfolding human tragedy in Pakistan is causing misery on a scale which calls the world to action. There simply must be a better response from the international community to prevent the spread of disease in areas affected by the floodwaters. "The action to date has not been commensurate with the scale of the crisis in Pakistan."
