Parents thankful for work on twins

LOS ANGELES -- The parents of the surgically separated Guatemalan twins happily thanked the doctors and nurses Wednesday who carried out the marathon, 22-hour operation, saying, "God will somehow repay them."

The 1-year-old girls once joined at the head remained in critical condition at the University of California, Los Angeles Medical Center.

"The future looks very bright now that the children are separated," the girls' father, Wenceslao Quiej Lopez, said through a Spanish interpreter together with his wife, Alba Leticia Alvarez.
