For Bosnian Teen-Ager, a Rape of Innocence : Soldiers: Muslim girl describes night of terror with abduction and multiple assaults by Serbs.

Dressed in jungle fatigues and armed with knives and guns, the guards scoured the dark, crowded room with their flashlights, searching for girls to abduct for the night. Then one of them noticed 16-year-old S.T.

“Get up,” he ordered, rifle in hand.

The teen-ager was led at gunpoint with three other girls to a covered green truck, where she was raped three times. She spoke on condition that she not be identified.

The triple rape of the Muslim teen-ager in June was only one among thousands, maybe tens of thousands, of assaults that officials of Bosnia-Herzegovina fear have been carried out against Muslim and Croatian women in the Serbian prison camps of northern Bosnia.

Reports of rape have been so extensive that some analysts think it is systematic. Sevko Omerbasic, leader of the Muslim community in Croatia and Slovenia, who is in direct touch with hundreds of refugees a week, has reached that conclusion. “There is more and more evidence that all the young women have been raped,” he told Newsday.

There are an astonishing number of reports of gang rapes of girls just above the age of puberty. And unlike S.T., who was released from the Trnopolje camp in late June, thousands of rape victims may remain in these prisons set up in schools and factories.

The Bosnian government estimated Friday that 200,000 people, mostly women, children and the elderly, are being held. Officials said they know of at least one or more camps reserved entirely for women and children, but they said that there is no way to estimate how many have been raped.

Bosnian Serb leader Radovan Karadzic denied that there are any detention camps for civilians in Bosnia and added that no women or children were detained at any location. Asked about the reports of systematic rape, he told Newsday: “There are six places in Sarajevo alone where they (the Muslims) are raping Serb women. We Serbs know what is going on.”

S.T.’s kidnaping and rape was a fairly speechless affair. The three guards were clean-shaven, S.T. said. Each had a “four S’s” tattoo on his hand, initials of the slogan under which the Serb military has committed mayhem in Bosnia: “Only solidarity saves the Serbs.”

The three soldiers and the four girls climbed into the back of the military truck, which came with a driver, and they stopped outside a gas station a few miles from the camp. S.T. was crying, and the guards left her on the truck. The other three girls, who were older, were led into a house that had once belonged to a prominent Muslim in the town and now served as a brothel for camp guards.

One soldier who had remained behind ordered S.T. to disrobe and lie down on the floor of the truck. He left his clothes on and forced her to have intercourse. When the first soldier was satisfied, he fetched his friend. Finally, the third one took his turn.

“What are you doing?” S.T. recalled asking the last of the rapists.

“That’s what your people are doing to us, as well,” he said in reply.

He thought a minute and said, “I’ll get you out of here.” Then he told her to get dressed. Before driving off, he called out to his buddies, “I’m going to get some more.” Then he drove her back to the crowded school at the Trnopolje camp and left her there.

He searched the room with his flashlight for other women, and the process began all over again. It was the second of three visitations that night.

In a way, S.T. was lucky. The other girls remained inside the brothel, and one of them told S.T. she had been raped by 12 men. The soldiers brought them back about 3:30 a.m.
