A Palestinian man was arrested on Thursday after security forces, acting on previously obtained intelligence, found an M-16 in the trunk of his car in the West Bank.
The 21-year-old Nablus resident was detained at the Tapuah Junction, an area that has seen several terror attacks over the past 14 months.
Since last October, 36 Israelis, two Americans and an Eritrean national killed in stabbing, car-ramming and shooting attacks. According to AFP figures, some 238 Palestinians, a Jordanian and a Sudanese migrant have also been killed, most of them in the course of carrying out attacks, Israel says, and many of the others in clashes with troops in the West Bank and at the Gaza border, as well as in Israeli airstrikes in the Strip.
The violence has waned in recent weeks.
The suspect was transferred to Israeli security authorities for interrogation.
M-16s are often carried by IDF soldiers, Border Police troops and some police units.
