Yes, Israel has checkpoints set up along its border with the P.A.,
Most check points are inside the West Bank.
[And this is exactly why the checkpoints exist, to curb the Muhammedan festival of attacking Jews, anytime they like.
Now, a 1400 year Festival even more of them participate in it.
When the Muhammedans choose Respect and Peace over killing Jews, then the checkpoints will be gone]
B'Tselem, a far-left Israeli group, that deals in human rights violations, publishes an on-listing ["
Checkpoints in the West Bank and Gaza"] which catalogues what you would expect from the name. Here's how it describes the checkpoint:
al-Walajah / Malha / ‘Ein Yalu
Permanently staffed Last checkpoint before Israel
Located on the Green Line. Staffed around the clock by the military, Border Police, and private security companies. Closed to Palestinians, with the exception of East Jerusalem residents.
In the very early hours of this morning (Friday), a little after 1:00 am according to
this Hebrew social media report, members of the Israeli
Border Guard (Mishmar Hagvul - the border security branch of the national police) did exactly what security personnel are supposed to do when everything works right: they spotted what they called a "suspicious" vehicle en route to Jerusalem right at the crossing. This one had yellow Israeli license plates, and on closer inspection was found to be driven by a pair of Palestinian Arabs who we now know are residents of Hebron and nearby Beit Jala.
Times of Israel says
Security forces arrested two West Bank Palestinians who tried to enter Israel with a pipe bomb Thursday night, police said. A statement from police said the “suspicious” vehicle carrying the Palestinians was stopped at the Ein Yael checkpoint in southern Jerusalem. A search of the vehicle yielded the homemade explosive device, a knife, and tens of thousands of shekels in
cash and checks, it said. An army sapper was called to the scene to defuse the pipe bomb. The suspects were detained for questioning.
Israel National News, quoting an Israel Police statement said
"Border Police soldiers and police officers are deployed around the clock in the Jerusalem area to locate and inspect vehicles and suspects in order to protect the lives of Israeli citizens."
The suspects have now been taken for interrogation. Neither they nor their weapons of war would have been intercepted if the checkpoint were not there (and they knew it was so they took an unsuccessful calculated risk) and the security personnel were less alert.
