The indictment, filed at a court in the southeastern city of Mardin, demands that the suspects be sentenced to life with no chance of parole on 44 counts of premeditated murder, the source told AFP on condition of anonymity.

They also risk additional jail sentences of up to 200 years for the 10 people injured in the May 4 carnage at the village of Bilge in Mardin.

The charge sheet demands 17 years in jail for another suspect who was not believed to be among the gunmen but who was found to be in possession of hand grenades during the investigation.

Prosecutors are continuing to investigate another suspect, who is a minor, the source added.

The trial is expected to start in the coming days in Mardin.

In the attack that shocked the country, masked gunmen stormed into Bilge, a small Kurdish village near the Syrian border, and opened fire just after a Muslim preacher had completed the wedding ceremony.

It was claimed at the time that the carnage was motivated by long-running hostilities between rival families.

The prosecutor said in the indictment that he found no evidence to support the claim, but offered no motive for the carnage.

Most of the suspects are members of the "village guard" -- a Kurdish militia force recruited by the government to help in the fight against separatist Kurdish rebels in the southeast -- and used government-supplied arms in the attack.

Settling disputes through violence are frequent in Turkey's Kurdish-populated regions, where feudal traditions persist.
