During an overnight raid, Israeli security forces seized from the family of a Palestinian terrorist who carried out a deadly 2015 shooting attack vehicles paid for with Hamas compensation, the army said Sunday.

The West Bank raid was part of a continuing crackdown by Israeli authorities against funding for Palestinian terrorists and their families.

The vehicles, estimated to be worth tens of thousands of shekels, were financed using cash Hamas gave the families of the terror cell that killed Eitam and Naama Henkin in a drive-by shooting in October 2015, the IDF said in a statement.

The statement did not identify which family of the four-member terror cell that carried out the attack was raided or where it took place. At least four of the terrorists came from families living in Nablus. It did not say how many cars were impounded.

The Henkins were driving with their four young children — the oldest was nine years old at the time — on the road between the northern West Bank settlements of Elon Moreh and Itamar when they were ambushed as their car slowed down at an intersection.

Four days later the IDF arrested four members of a cell over the shooting. In June 2016, all four were convicted and sentenced by a military court to two life terms and 30 years in prison each. During the investigation two other Hamas members were also implicated in organizing the shooting.

The money paid to the families was intended to be used to rebuild the terrorists’ homes that were demolished by security forces after the attack, the statement said.

Each of the families has so far received tens of thousands of shekels, the IDF estimated.

The Palestinian Authority also provides monthly salaries, usually via an intermediary organization, to the families of those convicted of carrying out terror attacks on Israelis or the relatives of those killed perpetrating such attacks. Israeli officials have repeatedly demanded that the payments be stopped, saying they amount to incitement to terror.

Legislative efforts are under way in both Israel and the US to cut funding to the PA if the payments continue.

In other overnight operations Saturday to arrest suspects in the Jenin refugee camp, 10 IEDs were thrown at security forces, the IDF said. Forces fired back with nonlethal weapons and identified two suspects who were apparently hit by the munitions.

Overall, 15 suspects were arrested in the West Bank for involvement in popular terror activities and violent rioting, the statement said.
