Autopsies on the bodies of nine Turks killed in an Israeli raid on an aid ship bound for Gaza are reported to have found that they were peppered with bullets and that many were shot at close range.
Britain's Guardian newspaper quotes Yalcin Buyuk, the vice-chairman of the Turkish council of forensic medicine, which carried out the autopsies for the Turkish ministry of justice.
He says the men were shot a total of 30 times.
One 60-year-old man was shot four times - in the temple, chest, hip and back, Mr Buyuk says.
A US-Turkish citizen was shot five times at close range in the face, the back of the head, twice in the leg and once in the back.
Two other men were shot four times, and five of the victims were shot either in the back of the head or in the back, Mr Buyuk says.
Conflicting versions of ship raid
The Israeli authorities and the activists have conflicting versions of what happened during the deadly pre-dawn raid on the aid ship Mavi Marmara on Monday.
Israel says its commandos only opened fire after coming under attack with clubs, knives, guns and other weapons.
Bulent Yildirim, head of the Islamic charity Foundation of Humanitarian Relief, which spearheaded the Gaza aid fleet, says activists used iron bars in self-defence after Israeli soldiers fired indiscriminately when they stormed the ship.
