Three infants were killed and eight others seriously injured on Monday when a fire broke out in a Bucharest gynaecology and obstetric clinic, local reports said.
The injured babies were in life-threatening condition, with burns over 50 per cent of their bodies.
The blaze broke out after an explosion in the incubator room. It was not immediately clear what caused the blast, but some reports point to a faulty air conditioner.
The Giulesti clinic for women is regarded as one of the top hospitals in the country and has recently been renovated and re-equipped.
