Tamil superstar Rajinikanth's condition is stable, but he has been advised two more days in the ICU, hospital sources said.

The 60-year-old, who is suffering from allergic bronchitis and fever due to exhaustion, was admitted to the intensive care unit (ICU) of St. Isabel Hospital Wednesday night.

"His condition is stable, but he will be required to stay at least two more days in the hospital, and a decision about his discharge will be taken only thereafter, " the hospital source told.

The south superstar has been hospitalised for the second time in a week. He was admitted to the ICU of the hospital after a bout of vomiting April 29, but was discharged in the evening.
