Money raised for the Disasters Emergency Committee’s Pakistan Floods Appeal has now hit the £9.5m mark - nearly twice the amount reported at the start of the week.
Brendan Gormley, chief executive of the DEC, described the response from the public as "overwhelming, particularly given the economic climate", but added that the vast scale of the disaster meant more was still needed.
"With monsoon rains continuing, the situation for millions of people in Pakistan is going to get worse before it gets better," he said. "We still need people to keep giving because the flood waters are still spreading fast and continuing to affect millions of people."
The DEC and its partners are now supplying aid to more than 500,000 people. Its funding appeal is separate to that of the UN, which is hoping to secure support from governments worldwide.
