After battling for survival for over three weeks at the All India Institute of Medical Sciences (AIIMS) here, two-year old baby Falak, who was taken off the ventilator, was again put back on it after she started having breathing problems Friday night.

"Falak is marginally better. But she was put back on the ventilator Friday night as she started having breathing problems," Dr. Deepak Agrawal, assistant professor of neurosurgery at the apex AIIMS trauma centre, told IANS Saturday.
