AURORA, Colo. (AP) — A Colorado hospital where a Minnesota woman gave birth to conjoined twins says one of the babies has died.

Amber McCullough delivered the twin girls, Hannah and Olivia, by cesarean section on Wednesday. Children's Hospital Colorado spokeswoman Elizabeth Whitehead says Olivia died after a 5-hour separation procedure.

Whitehead says Hannah is in critical but stable condition in a neonatal intensive care unit, and her mother is recovering.

The twins shared an abdomen, liver and intestinal tract. The girls had separate hearts and kidneys. Doctors performed the procedure 32 weeks into McCullough's pregnancy.

McCullough, a Hastings, Minnesota, native says in a statement that she believes in the power of prayer and the hospital's talented doctors.

She told KARE-TV in Minneapolis that Olivia was not expected to survive because of problems with her heart.
