British surgeons have successfully separated 11-month-old baby girls from Sudan who were born joined at the head.

When one of the twin's heart began to fail, their parents contacted the charity 'Facing the world' and they were flown to Britain to try and save them.

It took four operations at London's Great Ormond Street Hospital to separate the twins.

Weeks after their surgery, doctors are amazed that they are sitting up and smiling.
