IDF captures Hamas security chief, reports 29 Gaza ceasefire violations Aug. 19–Sept. 3

Israeli special operations forces captured Moein Muhammad al Arabeed, a senior Hamas security official, during a September 1 raid in the Katiba area of western Gaza City. Meanwhile, the US-backed Board of Peace’s stabilization plan for Gaza, which had led to a temporary reduction in Israeli strikes amid a tenuous ceasefire, seems to have stalled as strikes resumed recently.

The Israel Defense Forces (IDF) and Shin Bet intelligence agency did not initially name the Hamas security official. However, Gaza’s Hamas-run Interior Ministry identified him as Arabeed, the head of Hamas’s internal-security apparatus throughout the Gaza Strip. Videos captured part of the raid, which turned into a firefight when IDF soldiers were discovered. The Israeli Air Force struck several nearby targets “to remove threats” to the ground force, and the IDF reported no Israeli casualties. Gaza health officials said that the supporting strikes killed at least four Palestinians.

Israeli Prime Minister Benjamin Netanyahu described Arabeed as “one of Hamas’s most senior leaders” and said that he was responsible for concealing and moving Israeli hostages, hiding senior Hamas officials, rebuilding the group’s capabilities, and restoring its control over Gaza. The IDF separately said that Arabeed had recently worked to consolidate Hamas’s authority in northern Gaza and facilitate attacks against Israeli forces near the Yellow Line, which marks the Israeli military’s line of control inside Gaza.

Local reporting indicated that Arabeed previously served in Hamas’s Izz al Din al Qassam Brigades before transferring to the Gaza Interior Ministry’s security services. He eventually assumed command of the internal-security apparatus, which tracks suspected collaborators and protects senior Hamas leaders, earning him the nickname “the spy hunter.”

On August 28, US Ambassador to the United Nations Mike Waltz met Board of Peace High Representative Nickolay Mladenov and said that their priorities remained to “rid Hamas of its weapons” and restore governance under the National Committee for the Administration of Gaza (NCAG). The Board of Peace’s 15-point peace roadmap calls for Hamas and other armed factions to decommission their weapons, transfer civilian and security authority to the NCAG, and permit an independently verified, phased Israeli withdrawal. Israel has rejected the deal as Jerusalem insists Hamas fully disarm before the IDF cedes any territory.

Mladenov said that the Board of Peace had established a mechanism for deploying an International Stabilization Force to Gaza and identified potential deployment locations inside the territory. Morocco has agreed to participate in the force, while Israel has vetoed a Turkish contingent.

The plan has so far produced few concrete changes on the ground: Hamas has not surrendered its weapons or transferred governing authority, the NCAG has not entered Gaza, and only a small number of foreign personnel have arrived to prepare for the stabilization force.

The IDF reported 29 strikes and ceasefire violations between August 19 and September 3:

  • On August 19, the IDF said that it struck a Hamas platoon commander in Nuseirat who had infiltrated Israel during the October 7 massacre.
