The suspected murderer of 13-year-old Bat Ayin resident Shlomo Nativ was arrested earlier this month by the Shin Bet (Israel Security Agency) and the IDF, it was announced on Sunday. Mousa Tiet allegedly infiltrated the settlement in Gush Etzion on April 2 while carrying a knife and an ax. He attacked Nativ with the knife and killed him. He then attacked and wounded seven-year-old Yair Gamliel with the ax. On April 14, the Shin Bet succeeded in locating and capturing the 26-year-old Tiet, a resident of Khirbet Tzafah, 2 km. south of Bat Ayin. The Shin Bet said that during his interrogation, Tiet confessed and reenacted the attack for investigators, and revealed the location of the murder weapon, which he had hidden near the scene. Tiet told investigators he had planned and carried out the attack for "religious purposes" and in order to die a shahid, or martyr. He said he had purchased the weapons and hid them in a valley near Bat Ayin. On the morning of the attack, he collected them and infiltrated the settlement, first stabbing Nativ and then attacking Gamliel. He tried to attack a third child, who ran away. When residents tried to apprehend him, Tiet fled to his village. He told interrogators that he had destroyed some of the evidence and continued with his regular life out of the belief that he would not be captured. On Sunday night, the IDF imposed a closure on the West Bank and Gaza Strip that will last until the end of Independence Day on Wednesday. During this time, the army will facilitate crossings by Palestinians only for humanitarian purposes. Commercial crossings will also remain open.
