Conjoined twins who share a single body, two heads

An incredible footage shows a baby with two heads wailing in the hands of medics shortly after being born.
Sharing a single body and fitted with tubes, the clip of the newborns was posted on social media by surprised relatives towards the end of last week.
Born in Mexico, it is not known if the unidentified parents knew beforehand that they would be born with the deformity.
While it appears that they share all of their major internal organs, but have their own heads and brains.
But health officials have refused to go into detail about the rare case, instead just confirming that the mother is in a stable condition.
Doctors in the city of Ciudad Juarez are now said to be looking at a ‘plan going forward’ for the babies.
Siamese twins, or conjoined twins as they are known to medics, occur in about one in 100,000 pregnancies.
 Medical literature states conjoined twins develop when a woman produces just one egg that doesn’t fully seperate after being fertilised.
The developing embryo then begins to split into identical twins during the first few weeks but stops before the process is complete.
Experts say the partially separated egg then develops into a conjoined foetus.  
Most conjoined twins don’t survive because their organs are unable to support their bodily needs.
It is estimated that 40 per cent are not alive when they are delivered while 35 per cent die within a day of being born. 
Their birth comes just two days after a Saudi Arabia king promised to separate two conjoined sisters from Egypt.
The young girls, named Menna and May, will be treated at the kingdom’s expense, reports in the Middle East have stated.
King Salman al-Saud has ordered that the conjoined sisters are transferred to Saudi capital Riyadh, where evaluations will be carried out to determine if they can be separated.
