In pictures: Aid operation in Gujarat

Aid workers in Gujarat are focusing on improving sanitation and providing relief supplies to the victims of last week's earthquake. Relief agencies are struggling to distribute aid to those most in need.

Health officials say sanitation is becoming a problem.

Corpses decomposing under rubble are now posing a health risk.

Traffic jams, damaged roads and a lack of trucks are hindering the delivery of aid.

Aid agencies are drawing up a four-month plan to provide basic necessities.

Many of those injured are now receiving medical attention in makeshift hospitals.

Villagers in outlying areas are desperate for supplies

Kuntal Thakkar, 22, was rescued on Wednesday, but hope is fading for others trapped in rubble.
