A Sudanese woman delivered conjoined twins on Wednesday, who were born with separate heads, two hearts and one body.

This is a very rare form of partial twinning, known as parapagus dicephalus.

The babies were born in Kosti city in Sudan, in what was said to be the first birth of its kind in the country.

Because of their sensitive situation, the twins are currently being monitored by doctors in the intensive care unit.

Conjoined twin is a rare phenomenon, occurring 1 in 50,000-100,000 cases. Sadly, 60% of those cases are stillborn or die shortly after birth.

Meanwhile, Parapagus dicephalus affects one in a million births.

The world’s most famous surviving conjoined twins, with the Parapagus dicephalus condition, are Abigail and Brittany Hensel.
