Israel’s security establishment is increasingly concerned about the emergence of new armed Palestinian groups in the West Bank committing shooting attacks against Israeli checkpoints and settlements.

As the Israeli military continues its operations against these groups, specifically the Lions’ Den in the city of Nablus, these factions are gaining public support and luring more young Palestinians into their ranks.

Despite the Israeli arrest campaigns and raids in the West Bank as well as the killing of one of the the Lion’s Den’s leaders, Tamer al-Kilani, and the surrender of a number of the group’s members to the Palestinian Authority, the Lion’s Den continues to operate, and more groups have recently emerged, including one called the Black Cave.

In a Nov. 22 report, Amir Bohbot, military correspondent for the Israeli Walla news site, said that though the Lions’ Den group was dealt a severe blow, more armed groups and cells will crop up, according to Bohbot, who added that the Black Cave group brings together fighters spread across Palestine from Jenin and Tulkarem to Nablus.
