Israeli forces arrested six Palestinians in the area of Hebron in the West Bank during the early hours of Sunday morning, including the sister of the terrorist who stabbed and killed a 13-year-old girl in the settlement of Kiryat Arba on Thursday.
Mohammed Tra'ayra, 19, had praised terrorists and social media, even saying he wished to die a "martyr's death" before killing Hallel Yaffa Ariel, an American citizen, as she slept.
Tra'ayra's sister was arrested Sunday morning for allegedly encouraging the perpetration of terrorist attacks, according to Israeli security forces.
The Israel Defense Forces imposed a wide-ranging closure on Hebron and its environs on Friday after the attack that killed Ariel, affecting some 700,000 locals. The closure continued into its third day on Sunday.
Prime Minister Benjamin Netanyahu and Defense Minister Avigdor Lieberman approved the construction of 42 housing units in Kiryat Arba on Friday, following the killing of Ariel.
Two Israelis have been killed and six wounded in four terror attacks since Thursday. Two Palestinian assailants have also died.
