Arabs hurled a fire bomb at the fence of the community of Itamar in Samaria Sunday evening. The fire bomb exploded but no one was hurt and no damage was caused.
IDF soldiers began to comb the area and search for the perpetrator.
Residents were initially told to remain inside their homes as the IDF combed the area.
Last week, the Military Court in Samaria sentenced one of the Arabs who murdered five members of one family in Itamar to five consecutive life sentences and an additional five years in jail.
Hakim Awad, 18, of Awarta, and his cousin Amjad, murdered Ehud Fogel (36), Ruth Fogel (35), and their children Yoav (11), Elad (4) and Hadas, who was 4 months old. They were stabbed to death in their home at Itamar on March 12.
