The floodwaters are starting to recede - but they leave behind hundreds of thousands of destroyed lives, ITV News's Martha Fairlie reports.
Hundreds of thousands of people's lives are in ruins after devastating floods killed at least 1,130 in Pakistan, and left many more facing homelessness and hunger.
Labourer Rehan Ali was among those struggling to pick up the pieces in the southeastern Sindh province after the water finally began to recede, leaving devastation and misery in its wake.
He told ITV News he had been left homeless: "I don't know how to rebuild my destroyed house. Even I don't know how to feed my family.
"I lost everything. I don't know where to go. God help me."
International aid began to reach Pakistan on Monday after officials confirmed that more than 1,130 people have been killed by floods, brought about by the monsoon season, since the middle of June.
Disaster officials say nearly a half million people in Pakistan are crowded into camps after losing their homes in widespread flooding caused by the unprecedented monsoon rains in recent weeks.
The death toll prompted the country's climate minister to label the season as “a serious climate catastrophe".

In one of the worst single incidents of the flooding, at least 11 people were killed Monday when a boat that volunteer rescuers were using to evacuate two dozen people capsized in the flood-swollen waters of the Indus River near the southern city of Bilawal Pur, media reported.
An unknown number were still missing from the capsizing.The rains stopped more than two days ago, and floods in some areas were receding.

Thousands of displaced people have been taken to the safety of relief camps where aid is being provided.
Trucks carrying tents, food, and water arranged by Pakistan are also being dispatched to various parts of the country by the National Disaster Management Authority for tens of thousands of flood victims.
There are calls for more urgent help to be delivered by the international community, as many people displaced by floods say they not only lost their homes but their crops and small shops too.
Authorities say they were using military planes, helicopters, trucks and boats to evacuate people from marooned areas and deliver much-need aid to them.
However, many survivors complain they were still waiting for help or they received too little assistance from the government after being displaced, with some saying they got tents but not food.
Flash flooding from the heavy rains has washed away villages, prompting a mass evacuation effort from soldiers and rescue workers.
The Queen expressed sympathy for those affected by the floods, which will likely worsen Pakistan’s already dire economic situation.
"I am deeply saddened to hear of the tragic loss of life and destruction caused by the floods across Pakistan," she said in a message to the country's president.
"My thoughts are with all those who have been affected, as well as those working in difficult circumstances to support the recovery efforts."
Pakistan's Prime Minister, Shabaz Sharif, has vowed the government will provide housing to all those who lost their homes, as he said that the rains are the heaviest the country has seen in three decades.
Pakistan's National Disaster Management Authority reported the death toll reached 1,061 people, after new fatalities were reported in Khyber Pakhtunkhwa and southern Sindh provinces.
Officials say hundreds of thousands of homes have been destroyed after heavy rains and floods caused havoc across Pakistan.
The country was already in an economic crisis, with high inflation and a depreciating currency.
Sherry Rehman, a Pakistani senator and the country's top climate official, said in a video posted on Twitter that Pakistan is experiencing a “serious climate catastrophe, one of the hardest in the decade".
She said: “We are at the moment at the ground zero of the front line of extreme weather events, in an unrelenting cascade of heatwaves, forest fires, flash floods, multiple glacial lake outbursts, flood events and now the monster monsoon of the decade is wreaking non-stop havoc throughout the country."
"Going forward, I would expect not only the IMF, but the international community and international agencies to truly grasp the level of devastation," Pakistan's Foreign Minister Bilawal Bhutto-Zardari told Reuters.
Flooding from the Swat River overnight affected northwestern Khyber Pakhtunkhwa province, where tens of thousands of people have been evacuated from their homes to relief camps, set up in government buildings.
