Doctors confirm the twins born sharing a body but with separate heads did not survive long enough to receive treatment.
Footage of conjoined twins swept the internet yesterday. The babies shared all major organs, but each had their own head and brain.
Doctors at the Mexican hospital where the twins were born have now confirmed the babies did not survive.
Doctors are being careful to protect the identity of the family, but have confirmed the mother is doing well.
Conjoined twins occur when a developing embryo begins to divide in the womb but does not fully separate into two identical twins.
The survival rate for conjoined twins is often low because their dependance on shared organs can cause life-threatening complications.
