Israeli security forces captured two Palestinian cousins on Saturday for the murder of Israeli Dvir Sorek.

The two suspects, Nazir Salah Khalil Atsafra and Kassem Araf Khalil Atsafra, are from a town in the Hebron area, and Nazir has been linked to Hamas, according to a report on Ynet. Two other suspects suspected of aiding the killers were also arrested.

The IDF announced that the the car believed to have been used in the attack was also found.

Sorek’s body was found with stab wounds near his yeshivah at Kibbutz Migdal Oz, where he studied as part of a program that combines military service with religious studies.

Hamas accused the Palestinian Authority of aiding Israel in tracking down the killers.
