Israel Defence Forces have discovered an illegal weapons facility in the village of Saffa near Ramallah.
Illegal weapons manufacture and terrorist activity is an ongoing problem in the area.
The latest discovery followed Israeli police seizing a weapons hoard by a kindergarten in an Arab village close to Haifa.
Weapons included a “Carlo”-style submachine gun, stun grenades, flash grenade and ammunition according to Israeli Police. Police detained one suspect.
Meantime, security forces arrested 15 suspects involved in terror activities against Israeli civilians and security personnel on Sunday. The suspects were detained for questioning.
Soldiers also seized tens of thousands of shekels of terror funds.
