Survivors are cooking food in open air kitchens

Workers in the city of Anjar, in Gujarat state, have started using heavy equipment to clear the debris - a sign that they are no longer expecting to find anyone still alive.

"We talk about a limit of 100 hours, when after that the chances of finding someone alive drop dramatically," said Jochen Jakowski, the leader of a German rescue team in Anjar.

"It is close to a world record if we find someone after 100 hours."

In the town of Bhuj, near the earthquake's epicentre, a UK rescue team has rescued a 24-year-old man, who was was completely unhurt after surviving 103 hours with no food or water.

The focus for aid workers now is to get clean water, medical supplies, food and blankets to the survivors.

The stench of dead bodies hangs over the earthquake zone and cremations are being carried out around the clock.

As well as being an important ritual for the survivors, there are fears that poor sanitation will lead to an outbreak of disease.

Relief efforts

In a rare act, a military plane from India's long-time rival Pakistan arrived on Tuesday morning carrying 2,500 blankets and 200 tents for the quake survivors. More supplies are expected.

The United Nations Children's Fund (Unicef) has committed at least $8m in immediate aid.

Almost $5m will provide medical supplies and safe water for the estimated 100,000 people in need of immediate relief.

Unicef has already delivered tens of thousands of blankets, a million chlorine tablets for purifying water, and plastic sheeting for temporary shelter.

Sending in supplies

The UK, which has a large Indian community, many with families in Gujarat, has more than tripled its donation to $14.6m (�10m).

The government had earlier pledged $4.4m but raised it as the scale of the disaster became known. It has also sent a team of 69 rescue workers on a military plane to Ahmedabad.

Clean water and sanitation are priorities

France has sent a C-135 air force plane with two medical teams totalling 44 people and nine tonnes of material, including a field hospital and emergency food.
