The Kfar Saba Magistrate's Court sentenced Haj Yahya to nine months of imprisonment, seven months' probation, and a 5,000 shekel ($1,356) fine as part of a plea bargain.
The 24-year-old resident of the Arab city of Tayibe in central Israel supported the massacre on October 7 and praised the terrorist organization Hamas. Haj Yahya worked as a teacher's assistant in a kindergarten in Hod HaSharon.
"There is nothing more beautiful than waking up to the news of the Palestinian resistance in the Gaza Envelope and to the terror and fear of the Zionists from the missiles that fall on their heads," Yahya wrote on her Instagram account on the day of the attack.
Yahya confessed and was convicted of incitement to terrorism and identification with a terrorist organization.
