Flags were flown at half mast in the Indonesian city of Medan Tuesday in remembrance of 150 people perished by the Monday's air crash in the capital of North Sumatra.

The day was unofficially declared a provincial mourning for the victims.

The crash of a Boeing 737-200 with 117 people onboard was the worst air disaster in Indonesia since September 1997, when an Airbus A-300B4 crashed into a mountain in North Sumatra and killed all 234 people on board.

Thousands of people attended the funeral of North Sumatra governor Rizal Nurdin, who along with predecessor Raja Inal Siregar were listed among the death toll.

President Susilo Bambang Yudhoyono was slated to lead the funeral procession of Nurdin, who was in his second term as governor when the accident occurred.

The president is scheduled to inspect the scene and visited injured victims at hospitals.

The Monday's disaster miraculously left 15 survivors treated at three major hospitals in the city.

Xinhua learned that most survivors of the Mandala Airlines' ill-fated plane were being treated at the Glenneagles Hospital.

A 19-year-old woman underwent surgery for serious injury and a little boy managed to recover from minor injuries although he kept crying after the traumatic experience.

The forensic team at the Adam Malik Hospital has identified 65 of 139 bodies sent to hospital.
