Prime Minister Benjamin Netanyahu and his wife Sara traveled to the Ansbacher family’s home in Tekoa on Sunday night to personally tell the parents that their daughter Ori, 19, had been the victim of a terror attack.He spoke to them after security officials alleged that Arafat Irfaiya, 29, from Hebron has confessed to killing Ansbacher, 19, in Jerusalem on Thursday for for nationalistic reasons and had reconstructed the murder for police ahead of his arraignment in court.“It’s not surprising,” Netanyahu said. “But I wanted you to know this officially,” he added speaking in a low voice and holding his eye glasses in his hand as he sat in front of the family. They nodded at him as he spoke.“What seemed obvious, has also turned out to be real,” he said. Earlier in the day, Netanyahu pledged to deduct money that the Palestinian Authority pays terrorists and their families from the tariffs and duties it collects monthly on behalf of the PA and transfers to Ramallah.IDF troops meanwhile mapped the killer’s home ahead of its likely demolition. Troops entered Hebron before dawn on Sunday to measure the structure “to evaluate ways to demolish it,” the army said in a statement.Irfaiya was arrested in a joint operation by the IDF, the Shin Bet (Israel Security Agency) and the Border Police’s Yamam counter-terrorism unit in an abandoned building near the Jamal Abdel-Nasser Mosque in el-Bireh, which adjoins Ramallah, following intelligence received by security forces.At Ansbacher’s funeral in Tekoa on Friday, her mother Na'ama described spoke of her poetry and love of nature.“You were a child of light. You brought so much light and happiness to the house,” Na’ama said.Anna Ahronheim and Herb Keinon contributed to this report.
