Authorities in Pakistani-administered Kashmir said the new clinics, which offer free treatment, would nearly double the number of beds, which were available before the disaster.

"We have started rebuilding 61 basic health units and seven rural health centres with pre-fabricated materials in Muzaffarabad and the Neelum valley," local health chief Sardar Mahmood Ahmed Khan told AFP, referring to the capital of Pakistani Kashmir and a valley leading out of the city.

Groups including the United Nations Children's Fund and the UN Population Fund were helping the government with the work.

The earthquake killed more than 73,000 people in Pakistan and Pakistani Kashmir and seriously injured about the same number, many of whom still require treatment for broken limbs and other problems.
