Floods in Pakistan have devastated millions of communities in the northwest regions of the country, leveling homes and leaving families with no where to go.

The floods have killed 1,500 people and left seven million in need of emergency assistance, including medical attention, food and shelter.

In response to the disaster, international aid groups are distributing life-saving supplies to flood victims. The nonprofits working in the region need your help -- several organizations have launched an emergency appeal for donations needed to help Pakistanis.

British Red Cross disaster relief manager Pete Garratt said: "Thousands of people already have lost their homes and livelihoods, crops have been destroyed and whole villages have been washed away. "Roads and bridges have been affected, leaving some areas cut off, and with the flood levels due to rise there is a risk that many more people could find themselves homeless."

Aid is making its way to victims, but the process is slow and frustrating. Many Pakistanis believe their government has abandoned them, but according to The Los Angeles Times, Pakistani officials claim to be doing all they can.

"Dealing with such a large number of flood victims is not possible by the provincial government alone," said Khyber Pakhtunkhwa Information Minister Mian Iftikhar Hussain. "We need the help of the people, the federal government and international donor agencies."
