JERUSALEM (JTA) — A terror cell affiliated with Hamas in Gaza, which was planning terror attacks in Israel, was arrested in the West Bank Palestinian city of Kalkilya.

The six men arrested in a joint Israel Defense Forces and the Shin Bet security agency confessed to plotting a series of terror attacks against Israelis, the IDF said Sunday in a statement. The men also revealed where to find dozens of pounds of chemicals used to manufacture explosive devices, according to the IDF.

During the investigation, the cell members provided detailed information on the location of a weapons lab located in central Nablus in the northern West Bank. The explosives manufactured there were meant to be used against Israeli citizens, according to the IDF.

The Hamas operatives admitted to being recruited while staying in Jordan. They were then trained by Hamas in Gaza and transferred to the West Bank, or Judea and Samaria, for further terror and recruitment activities, according to the IDF.

They said they had been instructed to carry out terror attacks on Israelis during Israel’s Operation Protective Edge, the 50-day operation against Hamas in Gaza over the summer.
