It is over 20 million people affected by the flood now:

The flood is still on dangerous levels in several parts of Pakistan. The numbers of people effected by the flood have crossed 20 million. More torrential rains are forecast by the weather department. This is been considered one of the most devastating flood in world history. The UN has once again appealed for donations for Pakistan. But there has been a very slow response internationally to help Pakistan in this period of great devastation.

After destroying most of Khaiber Pukhtoon khawa and Southern Punjab, the water has now washed down the Indus River Valley, causing a deluge in Sindh. The water has been powered by unusually fierce monsoon rains that began in country’s northern areas some three weeks ago. 

Roads, bridges and other infrastructure have given way, overwhelming the government's ability to cope. At this point an estimated 1,600 have been killed with another 5 million left homeless.

The Labour Relief Campaign (LRC), launched in October 2005 after an earthquake killed nearly 100,000, has put up relief camps in several parts of Pakistan. The LRC springs into action whenever there is an emergency situation. Member organizations include Progressive Youth Front, Women Workers Help Line, Labour Education Foundation, National Trade Union Federation, CADTM Pakistan, Labour Party Pakistan, Pakistan For Palestine and Pakistan Kissan Rabita Committee. Currently the Lahore camp at Regal Chouck is raising thousands of rupees every day in aid.

Here is report of a union council in Khaiber Pukhtoon Khawa province by a team of four LRC members led by Farooq Ahmad, member of the federal executive committee, Labour Party Pakistan:

On 29 July Pir Sabaq, a Union Council of Nowshehra district, with a population of more than 34,000, is completely destroyed by the recent flood waters. A tent city of more than 1,000 tents has been established but most of the people are still forced to live in homes partially destroyed by the flood. This can lead to a major building collapsing any time, resulting in the further loss of lives.

In addition to losing their homes most people found their household items have been swept away. They have lost their cattle and goats as well. People without anything to eat, drink or wear.

Pir Sabaq is mainly a town of working-class people who work in marble or stone-crushing factories, or in the construction sector or agriculture sectors. When a LRC team visited yesterday, local people told about how water more than 14 feet high reached the town’s roof tops. Since the flood came around 4 a.m., while people were sleeping in the comfort of their homes, there was no chance to save anything but their lives.

The owners of small tourist boats did their best to help save lives of common people.

By contrast, when army helicopters arrived at the scene, they began evacuating the families of military men and residents of the big houses. People immediately saw the way the army discriminated about who they aided. People told the LRC team that many stranded on the roof tops of their houses waved their hands in the air when they saw the army helicopters coming, but it was of no use.

People have also blamed the government for failing to inform them on time about the danger of the flood. Some also charged that water was allowed to flow from the Warsik dam in order to save the nearby military camps.

The LRC team saw the house of Pervaiz Lala, general secretary of LPP in Pir Sabaq. It, like the majority, was completely destroyed; he and his family is now homeless. He told them the people did not eat for almost three days after the flood. Not a single governmental official has visited the area so far. The information minister of KP province, Mian Iftikhar Hussain, stated in clear terms that the provincial government cannot do anything to help people in this disaster. however two days before an NGO started providing some food.

There is still water all over Pir Sabaq. A bad smell is everywhere and no clean drinking water is available. The children are suffering from diarrhea and skin rashes. The local government dispensary, the only medical facility for the townspeople, has been totally destroyed. In this environment people are haunted by the possibility of diseases being spread.
