Jakarta – The Indonesian military has scheduled for Saturday the court martials of 19 soldiers suspected of gunning down student demonstrators on May 12, a report said Monday.

The head of the Jakarta military police, Colonel Hendarji (Eds: one name) said the first court martials for "indisciplinary actions" were tentatively set to start on June 6, according to the Antara news agency.

"But if they cannot be started on Saturday, then they will be held the following week," Hendarji said, adding that the postponment may be necessitated by further evidence and technical data needed for the cases.

Military Spokesman Brigadier General Abdul Wahab Mokodongan said last week that nine officers, six non-commissioned officers and four privates were involved in the "Trisakti case."

The finding followed an investigation into the shooting by a military team set up by armed forces chief General Wiranto after then-president Suharto stepped down May 21.

Security forces opened fire on a peaceful student demonstration in front of the Trisakti private university in Jakarta on May 12, leaving at least four students dead.

The shootings triggered widespread riots which left 500 dead in Jakarta and undermined the 32-year regime of Presdient Suharto. He stepped down in favor of his protege and vice president B. J. Habibie.

The head of the national military police, Major General Syamsu Jalala, has said the 19 soldiers have been in military detention since May 28.

The military said that only four students were shot in the Trisakti incident while the university said six were killed.
