Pakistan's annual monsoon rains have reached all five of the country's provinces, affecting millions of people.

The non-stop rain has caused river banks to burst, releasing torrents of water that has obliterated everything in its path.

More than four million people are displaced and at least 1,600 people have been killed, a number that may rise as bodies are recovered from the rivers.
