Three-week old conjoined twins died on Saturday due to pneumonia and infection.
According to doctors at the Multan Children Complex, the two children could not be separated surgically as their hearts, livers and digestive systems were intertwined. Moreover, they had a bacterial infection in their chests.
The two girls, daughters of labourer Nazeer Abbas, were born January 14 and due to lack of resources, the doctors were helpless to treat them.
A medical board formed on the directives of the Punjab Health advisor had announced that it was impossible to separate the girls.
Also known as Siamese twins, conjoined siblings are twins who in rare cases, about one in 200,000 live births, are born with their skin and internal organs fused together, according to the University of Maryland Medical Centre website.
About half are stillborn, and the survival rate is between five and 25 per cent. They develop from a single egg, which splits in the case of healthy twins, but not fully in the case of conjoined siblings.
