An Israeli army prosecutor says five soldiers beat a Palestinian detainee for 15 minutes, tased him and that one soldier inserted an object into the detainee's rectum.

The prosecutor spoke in a hearing held on Thursday on the prosecution's request to extend the soldiers' arrest. They are suspected of abusing a Hamas police officer arrested in Gaza and taken to the Sde Teiman military facility.

The prosecutor described in graphic detail the abuse the soldiers allegedly engaged in, which resulted caused the puncturing of the prisoner's rectum and the fracture of ribs.

According to the prosecutor, three of the soldiers, including two reservists and their commander, approached the sleeping prisoner, woke him up and pinned him to a wall.

After the prisoner fell to the ground, one of the suspects was joined by other soldiers and beat the prisoner with a club for 15 minutes. They dragged him along the floor and electrocuted him with a taser, the court was told.

At that point, one of the soldiers inserted an object into the prisoner's rectum. The suspects also allegedly warned him not to complain to the authorities about the incident. The evidence in the case is based on 100 separate testimonies, the prosecutor said.

The prosecution asked that the five soldiers, who are under house arrest, are to remain under those restrictions for another two weeks. The investigation of the case is expected to be wrapped up shortly. Evidence is expected to be provided to the suspects' lawyers at the beginning of next week, the army said, after which defense lawyers are entitled to ask for pre-indictment hearings for their clients.

Late last month, following the detention of nine soldiers in the case, about 200 people protested outside the Beit Lid army base in central Israel, where the military court is located, demanding the soldiers' release. The protesters stormed onto the base and entered the military court building.
