Abu Khedair's mother, Suha, said she wants equal justice for the people who abducted him in the early morning as he was heading from his home to a mosque for prayers. He died after being burned alive and hit on the head with a blunt object, authorities say.
"If they sentence them and demolish their houses and give them life sentences, it might satisfy me a little," Suha Abu Khedair said.
The Israeli military destroyed the homes of the two main suspects in the killings of the three Israeli teenagers. Those suspects are still at large.
Palestinian Authority President Mahmoud Abbas has called on the United Nations to set up an international investigation into recent crimes against Palestinian people, including the killing of Abu Khedair, the Palestinian state news agency WAFA reported.
Officials from both sides have called for restraint amid fears that the cycle of horrific violence could continue.
