In the city of Ahmedabad in the Indian state of Gujarat, there is growing concern for thousands of Muslims still sheltering in makeshift camps almost four months after fleeing from their homes.

Ahmedabad saw much violence during the riots

The government says it will close the relief camps by the end of June but many of the people there either have nowhere to go or are too frightened to leave.

About 150,000 Muslims took refuge in compounds attached to schools and mosques after religious violence broke out in late February.

Most have left, but the fate of those still seeking shelter has become uncertain.

The government says the camps must close when it stops supplies of water and food.

Nowhere to go

As another incentive, some food rations will be continued to help people who go back home.

Many people are still homeless

Many camp organisers are also trying to persuade people to leave.

Some are said to be overwhelmed by how long this crisis has lasted.

What was envisaged as a short-term need for shelter and sanctuary has become a long-term commitment, made all the more difficult by the onset of the monsoon rains.

But some non-government groups working with the displaced people say they simply do not have homes left to return to and need more support.

Many Muslim homes and businesses were burned down and possessions looted.

Financial help

The government is giving compensation to victims of the riots, but some Muslims complain it is too little.

One man said it was not even enough to buy plastic sheeting to protect a family from the rain.

As well as practical difficulties, those working with the displaced people say there is still a mood of fear and insecurity despite assurances from the government that they are safe.

There is also disagreement about how many people are still in the camps.

Government officials say there are fewer than 19,000, but many local journalists put the figure at almost 50,000.
