Israeli security forces prevented a Palestinian cell from carrying out an attack on mispallelim at Kever Yosef, the Shin Bet security service said Tuesday.
The authorities said they arrested four Palestinians who were planning a bombing and shooting attack on visitors at Kever Yosef, adjacent to Shechem.
A gag order on the arrests was lifted Tuesday, though it was not stated when the arrests took place.
According to the Shin Bet, the suspects were provided with arms and directed by the Gaza-based Islamic Jihad group and were making their plans with a level of professionalism.
The four were named as Nassim Damiri, 30, of Tulkarem, a Fatah operative who has been jailed repeatedly; Mahmed Damiri, 23, of Tulkarem, a Palestinian Authority police officer; Yasser Tzarawi, 25, of Rafidia, a Hamas member with a criminal record; and Adwan Nazel, 24, of Qabatiya, an Islamic Jihad member.
In 2011, a Jew was shot and killed by Palestinian police after trying to enter the kever without prior permission from Israeli authorities who supervise access to the site.
