Jerusalem (CNN) A 13-year-old Israeli-American girl was stabbed to death in her bedroom Thursday morning in the West Bank settlement of Kiryat Arba, a spokesman for the Israel Defense Forces said.

Hallel Yaffa Ariel was sleeping when a Palestinian teenager entered the house in the settlement near Hebron and killed her, authorities said.

"Just like any teenager on summer holiday, my daughter was asleep, calm, relaxed. A terrorist murderer came and murdered her in her bed," her mother, Rena Ariel, told Israel's Channel 2.

Security guards on the settlement entered the home and found the suspect still inside, the IDF said. During a fight, one security guard was stabbed, and the intruder was shot and killed.

The Palestinian Ministry of Health identified the attacker as Mohammed Tarayra, 17, from Bani Naim, a village east of Hebron.
