Border police Wednesday found a knife hidden in the sock of Palestinian teenager who tried to enter the Tomb of the Patriarchs in Hebron without going through a metal detector.
The suspect, 17, was stopped and searched at the holy site in the West Bank city.
Security forces found the knife during the search.
The suspect was detained and taken away for questioning.
The flashpoint city of Hebron, where Palestinians live in close proximity to settlers who are guarded by Israeli troops, has been the scene of numerous stabbings and attempted stabbings since a wave of attacks carried out by Palestinians began in October 2015.
On Sunday, IDF soldiers arrested a Palestinian man who was carrying a knife as he approached the the Jewish settlement of Mevo Dotan in the northern West Bank.
He was arrested after the soldiers ordered him to surrender.
