Weeping and crying out the names of the dead, thousands attended the funerals of seven Israeli schoolgirls shot and killed by a Jordanian soldier on their field trip to the "Island of Peace" on the Jordan River.

Classmates of the victims gathered today at the Fierst School in the central town of Beit Shemesh, sobbing at their desks and hugging each other on hallway benches as they studied newspaper photographs of the slain students. About 1,000 students prayed together before splitting into small groups for counseling by social workers and psychologists.

"The most important thing is to be together," teacher Zohara Menzigi said.

The shooting on the Jordanian island that Israelis call Naharayim, 55 miles northeast of Tel Aviv, came at a time of crisis between Israel and Jordan over the impasse in Israel's peace process with the Palestinians.

At one of the funerals Thursday, Prime Minister Binyamin Netanyahu said the massacre would not frighten Israel into easing control of war-won land -- defying a warning by Jordan's King Hussein just days before that such a stand could bring violence.

"If someone thinks that the murder of little girls will defeat this people, he doesn't know {us}," Netanyahu declared at a cemetery in Beit Shemesh. "If someone thinks he will break our spirit and that we will give up . . . our holy land and our eternal capital, he doesn't know the great strength in every person around me here."

Wailing, mourners placed pebbles on the fresh graves of four eighth-graders, in accordance with Jewish tradition.

"Keren, where are you?" the family of junior high student Keren Cohen shouted.

"Adi, the beautiful," others cried. Family members said the girl was fluent in sign language and served as her deaf parents' main link to the world.

The gunman, army driver Lance Cpl. Ahmed Mousa Daqamseh, 28, had psychological problems and Jordanian military police found tranquilizers in his possession, his father, Mousa, said today.

"He was always secluded, and he looked always sad and lonely," the elder Daqamseh said.

A high school dropout from the village of Ibdir, the gunman was drafted 12 years ago, his family said. He had two sons and a daughter but no history of violence and was not affiliated with any political group, family members said.

"We're shocked by his action," Mousa Daqamseh said as tears flowed down his cheeks.

"My boy was unstable," Daqamseh's mother added. "He had a psychological problem and used to have anxieties."

She refused to give other details except to say: "He used to sit alone and stare in the open and think. He used to get angry sometimes, but cool down after a long walk."

Hussein said he called Netanyahu and asked to visit the families of the victims. The two countries are trying to arrange such a visit, a source at Israel's embassy in Jordan said today.
