"The women died after severe hemorrhaging and we believe the most likely cause might be an infection after they were administered tainted IV fluids," a hospital administrator told the BBC.
"During lab tests, we found three batches of glucose, which were tainted. We have lodged a complaint with the police and strict action will be taken against the manufacturers."
The report said India has the world's highest maternal mortality rate, with critics saying most pregnancy-related deaths can be prevented with more care and better treatment.
