"We have closed the operation theatre temporarily because we don't know the cause. Alternative arrangements for deliveries have been made," said hospital superintendent Dr C Suresh Kumar.
"In the last ten days several (cesarean section) deliveries took place...But only these five women were affected. We have appointed a committee to look into the matter. It is unusual, so much mortality is not expected. The reasons need to be investigated," Dr Kumar told PTI.
Earlier in the day, relatives of one of the deceased women staged a protest on the hospital premises alleging negligence on part of the hospital.
