Siamese twins joined at the head left Iran for Singapore today for medical tests and possible surgery to separate them after 28 years of shared life.

One of the Siamese twins whose fused skulls were separated in a landmark operation in Singapore has recovered enough to take her first ride in a pram, a hospital spokeswoman said today.

Ganga Shrestha was fighting for her life in a Singapore hospital today, 10 days after surgeons separated her brain from that of her Siamese twin sister in a landmark operation.

A second set of parents face the ordeal of looking after Siamese twins, the day after two babies were successfully separated.

Surgeons are still operating to separate eleven-month-old Siamese twins from Nepal who are joined at the head.
