The three Bethlehem residents, aged 17, 20 and 21, were carrying two knives and an ax. In an initial interrogation, they said that they were sent to stab security guard in exchange for money.
The three were taken into interrogation at the Jerusalem District Police's Minority Department and their weapons were confiscated. It is still unclear who sent them to the checkpoint and how much money they were promised in return for the terror attack.
Earlier Friday, Border Guard officers uncovered two pipe bombs near the force's post south of Jerusalem. A sapper was dispatched to the place and detonated the devices in a controlled manner. Border Guard forces patrolled the area in a bid to locate other bombs.
Stabbing attempts against security forces are being launched continuously. About a week ago, a Border Guard policeman was lightly injured in his neck after being stabbed by a young Palestinian in a checkpoint near Jerusalem.
The young man pulled out a knife, attacked one of the police officers, and was stopped by the other officers.
