With the death of another infant on Tuesday at a government hospital in Larkana, the number of shocking deaths of newly-born babies climbed to 15 over the past four days.
The babies died because of power failure and subsequent interruption in oxygen supply.
The Sindh government has ordered a probe into the deaths. Officials said the governor and chief minister Sindh have separately summoned details of the incident.
Sources said five children in intensive care unit on Friday night died after the power failure in the hospital. The administration attempted to kick-start the standby power generators but it also failed because there was no diesel in its fuel tanks.
In the absence of backup for oxygen supplies, the babies could not be saved, they said.
On Saturday, eight more babies died as they could not get medical treatment because of power outages and administrative issues at the hospital.
One infant died on Sunday and another died on Tuesday, bringing the death toll to 15 over the past four days.
