Pakistan floods: Eyewitness accounts
Rain and floods are causing massive disruption in the southern Pakistani province of Sindh for the second year in a row.
Rural areas are worst hit but Karachi has also been paralysed, with schools shut and vehicles abandoned, although the city is now limping back to normal. Here, BBC News website users tell about their experiences of the flood waters.
Saad Ali in Karachi
Right now the drainage is working in Defence, which is one of the most well off areas: when the rain stops, even for an hour, the water drains away.
That's part of the improvements in this area in the last few years, but if it rains continuously for two or three days, the drains will get blocked.
Some areas do cope and others don't. I've seen places where half the street is flooded but the rest is not.
The rains affect rich and poor alike but it's safe to say that in the poor areas, in particular to the north of the city, they have been far worse affected.
Because the housing is less established and the drainage not as good, the water hasn't drained from the land as much.
We've been told to expect heavy rains which is why the schools have been closed and people told to stay at home for their own safety.
Lutful Mannan in Kunri
I live in Kunri town in Omarkot district. My village is a few kilometres to the south.
The area up to my village is only partially affected, but beyond that it is water as far as the eye can see. Almost 95% of the people in the area have moved west, towards the desert.
Very few people are left behind, and they have erected plastic shelters wherever they find high ground. For about seven or eight days of rains that continue to lash the area, I've been sleeping with these people.
We have been keeping a watch on protective embankments in the area so that no one drives a breach into them and shift the flood waters to our side.
It is horrible out there. These people are without drinking water. There's no food. And mosquitoes make it literally impossible for them to get some sleep at night.
In addition, carcasses of dead animals litter the area. There is a foul smell in the area all over the place.
People from the desert bring similar news. To the south, where there were roads, people now use boats to commute. We've been sending food from Kunri to areas as far south as Naukot (50km away), using boats.
There is no help coming from the government. The army is there but they only offer rescue services, nothing else.
Adnan Dhanani in Karachi
I live in the Bath Island area of Karachi, it's one of the better or posh localities of the city.
Properties in my locality have been flooded following a heavy rainfall. The amount of water that came down during the last four days has been horrendous.
Many roads have become impassable and most streets are under four inches of water.
The slums have been hit hardest. The whole city is in lockdown mode. Everything is shut, which is an inconvenience for city dwellers.
Fortunately, I've stocked up on food and other supplies.
