A "never-ending disaster" is how a U.N. official is describing the situation in Pakistan after the devastating floods of this year's monsoon season.

The U.N. says more than 3 million people have yet to receive the food aid they desperately need, while the Pakistani government says nearly 1 million have received no help of any sort. The country's disaster agency is appealing to international donors to send tents, ambulances, mobile clinics and hygiene kits.

The lack of aid has led to anger against the already-fragile government and that's further hampering relief efforts. The Red Cross has twice halted aid distributions after being confronted by mobs of people upset they were not getting enough.

Part of the problem is the scale of the crisis. The floods that began as a slow wave of destruction across Pakistan at the end of July, swamping as much as one-fifth of the country and leaving 8 million people dependent on aid, according to the U.N. and the number keeps growing.
