JERUSALEM (AP) An Israeli military court opened an initial hearing Tuesday for nine soldiers detained over what a defense lawyer said were allegations of sexual abuse of a Palestinian at a shadowy facility where Israel has held prisoners from Gaza during the war .

The investigation has stoked tensions between the military command and hard-line nationalists in Prime Minister Benjamin Netanyahus government who advocate an even harsher hand in Israels conduct of the 10-month-old war in Gaza.

The probe into the incident at alleged torture center Sde Teiman has stoked tensions between military command and hard-line nationalist politicians who want more violence.

The soldiers detention Monday triggered angry protests by supporters demanding their release, including members of parliament and at least two government ministers. On Monday, several hundred protesters broke into the facility in southern Israel, known as Sde Teiman, and then later into the military base where the soldiers were being held. Video showed them scuffling with troops before being forced out.

Defense lawyer Nati Rom, who is representing three of the soldiers, said they were innocent and described the alleged abuse they are accused of committing as acts of sodomy. The military has given no details on the investigation, saying only it was looking into allegations of substantial abuse.
