Concerns that charities linked to militants are filling an aid vacuum in flood-stricken Pakistan has galvanised the US government into stepping up its own relief efforts.
The White House says its tripling the number of helicopters its sending to help distribute tents and food supplies.
But the Pakistani authorities now believe fresh rainfall in the north is set to trigger more waves of flooding already surging through remote areas.
The news came as the UN Under Secretary-General for Humanitarian Affairs launched an appeal for 350 million euros.
“Unless aid activities continue to be rapidly scaled up to reach those who remain displaced and without immediate access to food and clean drinking water, additional loss of human life and further suffering will occur,” said John Holmes.
Pakistan’s worst ever flooding has already affected 14 million people, leaving 2 million homeless and an estimated 1,600 dead.
Pakistani military helicopters have been deployed to rescue villagers stranded by the floodwaters and to drop aid packages.
But for some it’s just not enough. With hospitals washed away one mother had no choice but to give birth at a train station.
