The Home Minister said young and experienced doctors were working round the clock to save the lives of the injured.

Chidambaram said he has spoken to the relatives of the injured and assured them that the doctors conveyed that the best possible medical attention would be given to every injured.
"In case, a family wants to take the injured person to a hospital after one or two days, we will ask the doctors opinion and if the doctors say that they have to be shifted, they will be shifted to the hospital of the choice of the family," he said.
The Home Minister said his Ministry officers were stationed in the hospital and making a list of the injured.
