AUSTRALIAN university student Ahmed Luqman Talib was allegedly left to bleed for 12 hours after being shot in the thigh by Israeli commandos during their raid on a Turkish aid flotilla near Gaza on Monday.

The 20-year-old, who suffered severe blood loss, was last night in intensive care in an Istanbul hospital.

He was evacuated by air ambulance from Israel to Turkey, but Israel refused to hand over his medical records.

His father, Luqman Talib, who rushed from Kuwait to his son's bedside, said he and Australian consular officials had repeatedly requested the medical documents, and the lack of information about surgery performed in Israel was now complicating his son's treatment.

''Ahmed was left to bleed for over 12 hours before medical treatment was availed to him,'' Mr Talib told The Age.
